Asking like in places like this is a good start. There is of course a wealth of information out there and different ways to approach it.

The things I would consider are the following:
* What are your skills?
* What has already been built?
* Are you bootstrapping or looking for funding?
* What type of product is it?
* Can you earn a dollar from it today?
* Do you have a team that can iterate quickly?

I've been through a lot of these types of conversations and would be happy to chat if you need to.

Thanks,
Greg
