Depends how far along you are. You can always hold off on incorporating until you have a term sheet or ready to get your docs signed.

Of your options: 1. If you end up taking legit money, you'll want regular counsel. Cooley is great.

2. Stripe Atlas is only $500 and takes a couple days. But as soon as you raise money, big law lawyers will update your agreements so you're back to step 1.

Also, remember. Most big law firms will offer you a fixed price for the initial incorporation and financing. Don't be afraid to ask.
