If you are talking about incorporation, that costs next to nothing and takes little time. Just do it yourself.
Other than that, it depends how you value your equity. That is, read http://www.paulgraham.com/equity.html
Regarding incorporation, do you have any suggestions as where to start?
Thanks for responding.
Sounds like a red flag to me. It seems like they're looking out more for themselves than for you and your business, unless for some reason they are super excited about your idea and think it needs a lot of VC cash ASAP to move forward.
Frankly, I'd prefer to incorporate on my own and don't want to get too far ahead (i.e VC meetings) while assuming the law firm will cover my ass.
