Hi all I have a question regarding a client... she wants to see what I can do so I need to create a logo and website comp for her. Looks like she won't pay me until she likes what she sees. I have an online portfolio that shows my work and what I can do. Should I request some sort of payment for the comps or do the comps for free? And see if she'll hire me afterward should I take that risk.

Any advice would be great.
