This contractor has 0 reviews on yelp which I found a bit sketchy, but was able to vet him by his contractor's license, worker's comp, and by visiting some of his ongoing projects.

I'd pick a market close by, or that you have a strong personal connection to, or that you visit often.For example, these investors bought properties that "weren't very expensive," or at least didn't look that way:https://www.biggerpockets.com/forums/12/topics/1215726-break...https://www.biggerpockets.com/forums/963/topics/1195280-expe...https://www.biggerpockets.com/forums/48/topics/1137397-balti...

Just know that it is a "no days off" kind of business and very mechanical.I would suggest documenting your process via video so that eventually you can bring people on to replace the different hats you will be wearing.Keep in mind of these 5 components of any wholesale business.lead generation, deal sourcing, underwriting, marketing, transaction coordination.

What kind of construction project? 

I assumed this would be the case because the rest of what California has to offer kind of sucks.

I don't know exactly but some kind of % would be fine.
