Ph.D statement asking for funding (UK)

[LeahPhil.]

Hello to all,

The University of Edinburgh has offered me admission to the 3year Ph.D program of Philosophy but no news on funding. I need to apply for several scholarships but I have no idea how to write a statement of purpose (300-500 w) asking for funding. Any tips? 

Also, any tips about the Uni. or the department or about (UK) scholarships in general would be helpful.

Thanks in adnvance
