Was wondering if anyone knew of any freelance graphic designers/students, preferably in the London area?

I need a logo designed within the next month or so, and have been given a certain budget for its production. Students might like this, please link to people's portfolios if you know any.

The kind of stuff I've been looking at:

Kate Moross

Neill K

Anything would be helpful though as there is no design plan and I do a science subject at university, not artistic at all!
