Contract for Passive Investors

[Stephen Grindle]

Hey all, my business partners and I want to start inviting passive investors into our deals in order to speed up the process and not have to use banks for all of our funding. A couple of questions related to this: 

1. Does anyone have a sample contract/agreement they can share that they use with their passive investors?

2. What kind of legal processes do we need to set up other than an LLC? (We already have an LLC)

3. Are there limitations on inviting too many investors in to fund a single deal? Basically, do we have to fund one deal with one investor, or can we include several investors on a single deal? 

Thanks!
