I think it's pretty simple...

You can do one or the other but not both; inspection or be the general contractor.

If you inspect the home for a fee... you are obligated to step out of the general contractor roll due to having a monetary interest (think-- the more you find, the more the contractor would get to fix. That's certainly a conflict of interest).

If you are going to be the GC, then you should quote the job with your company's profit margin already built into the quote--without expectations of splitting the profits. Additionally, there should be some incentives of bringing the job in on-time. The sellers budget is nothing, as a general contractor, that you should be involved with. The quot you provided and eventually agreed upon with the investor has your payment built-into it.
