Gut feeling says no, but money says yes.

I've run into a problem recently, a client of mine has me writing some intricate front end software for robotics, and has been quite late and delinquent on getting me the source code of the machines, so that I can properly communicate between them.

I just received and e-mail from him that he wants me to set up an e-commerce lingire (sp) website, as in naughty costumes, in time for Halloween. I'm uncertain of how to proceed.

The front end is for a flat fee, part on completion, part on the first order filled.

The site is for a percentage of profits, and a partnership.

I've just started working freelance, in fact this is my first client, and I'm very uncertain of how to proceed. Feel free to contact me any way possible, as I need a rather speedy decision.
