Carey,
I think you presented a good offer and should give it a bit more time to find the right match.
Don't forget that you are looking for someone who has the $ to buy the house to begin with. Also dont forget that someone who has the cash typically already has a team they go to as it is, so you need to find someone who is unhappy with their current contractors or is new to the game and doesn't have any loyalty to one team or another.
So your offer is good, but your potential market is "small", relative to the size of readership of the Marketplace forums...
What might help kick start your foray in real estate is to actually try and find a deal on a house first (even though you dont have much experience), then look for $$$ partner.
If you can present the deal with a house potentially bought right (good price, good area, enough room for rehab, and good profit) with the fact that you can handle the entire rehab process and "all" they need to do is front the cash for the house...
Use the fact that you will be investing your own cash in the rehab costs (labor/materials) as your portion of "skin in the game".
Maybe some of your contractor buddies or acquaintances have some leads on heavily distressed properties in SFV that you can steal.
Everyone is always scared of heavily distressed properties, but both you and I know that they are typically "easy" fixes.
