So here's the situation. I apologize if something like this has already been answered elsewhere, or if I'm posting in the wrong forum, but I figure that I'd like to get this feedback rather directly. 
I'm strongly considering the MPP program at the McCourt School at Georgetown, as it'll allow me to work while I'm attending. And specifically, I'd like to specialize in something pertaining to environmental/energy policy, or failing that, something Sustainability-related. By way of background, I already have a degree/certificate in Sustainability from UCLA, so I already have some academic training/experience in both fields. 
The kicker here though is that I'm not getting any financial aid or scholarships otherwise from Georgetown at the moment, so if I choose to go, I'd be on my own. However, I do have enough savings lined up, and my parents are willing to help me to some extent to pay for tuition and keep my student loans to a minimum, so attending Georgetown isn't totally out of the picture just yet. That's also where working while attending the program factors in: by staying in my full-time job, I can at least defray expenses to some degree. 
So I guess that for the purposes of this question, you can divide it into two parts. For those of you who have either attended McCourt and/or have experience in environmental/energy policy:
Does Georgetown have good enough career services/connections so that I can reasonably find a good job after graduation? More generally, I understand that with the renewable energy sector, it's on track and already becoming the fastest growing source of energy production in the US, but does this also translate into lucrative job opportunities for public policy graduates with specializations in those fields? Specifically, in that sense, I'm looking into working on cap-and-trade programs  and other climate change mitigation/adaptation programs in the public sector, and if we're about the private sector, I'd be interested in working for consulting firms. I can imagine that with climate change being as serious an issue as it is now, state and local governments would be quite willing to step up their efforts in dealing with climate change and consulting firms would be all the more willing to advise them on how to do so, respectively; this would hopefully translate into more jobs. Are these estimates at all realistic and/or plausible? Since I'd be paying out of my own pocket to attend McCourt, and because loan forgiveness programs aren't what they appear to be at all, I just need to know, in short, whether this kind of investment would be worth the cost. If I do end up specializing in environmental/energy policy, is there a good chance that I can find a decent-paying job that can help me minimize any possible student loans as much as possible? And to be clear, it's not just about the career opportunities for me here; I do in fact enjoy studying those fields given my experience at UCLA studying them. 
Any constructive criticism, feedback, and responses would be greatly appreciated. 
Good luck!

I've got a unique situation that I'll explain below. But before we get started with that:
GPA: 3.47, BA in English from a UC.
GRE: Verbal score 162, Math score 162, AW score 6.0  
Work experience: 5 years paralegal work substantial experience in environmental litigation/policy, another 2 years of paralegal work this time in-house for a hedge fund. 
Program: MPA, MAYBE an MPP.
Age: 27
Quant coursework: Microeconomics and Statistics, at both the undergrad at graduate level. 
Desired Policy concentration field: either environmental or global policy, possibly both concurrently. 

Here's the real kicker. I actually DID start an MPP program about 2 years earlier (let's just say it's a top-10 program; certainly Harvard-level), but I was dismissed after just my first semester because of poor performance. I didn't fail anything outright and even got credit for these classes, but my aggregate GPA wasn't good enough to pass muster (Bs and Cs, basically). What happened was essentially a combination between having difficulties adjusting back to school after a 5-year gap (the first paralegal gig) and long-term burnout (I kept up a rigorous study regimen for 3 years before matriculating; you eventually hit diminishing returns if you keep this up without any real resting period). Since then however, I've done well at my current hedge-fund paralegal job to get at least 2 LORs, and I'm still on good terms with one of my old MPP Professors, so that's another LOR. Most importantly, I've taken for-credit graduate courses in the same subjects that did me in 2 years ago and aced them this time, so hopefully that'll at least show some growth and improvement to the admissions committees. 
That being said, my school choices are:
HKS (MPP), Cornell (MPA), Georgetown (MPM), SUNY Albany (MPA), SIPA (MPA), USC (MPA), UVA(MPP)
I know that many of these choices might seem prosaic given my previous SNAFU, but I'm still willing to try and give it my all. What are my chances in light of all this? Thanks.
