You should get people in the trades to do a good portion of that sort of work. 

Potentially you could sell the lots to the same builder that builds the two residences and work out some sort of trade. 

People don't value the time trades spend off the job; estimating materials, driving to jobs, getting materials, permit works, continuing education, following up on paperwork etc. 

Since most people are passionate about financial independence, I figure at least some of you may be interested in day trading!

One great way I've found people is through local Facebook groups (Local Small Business Groups &  Local Buy/Sell/Trade groups).

So in that sense, no, there isn't any risk for you paying a reasonable down on a project, there is actually considerable risk if your hiring desperate persons who will do whatever to make what they can, I remind you we are in a labor shortage nationally, generally speaking, good trades professionals don't "need" any work from any 1 person. 

Trades (carpentry, electrical, plumbing), accounting, etc are all jobs that are in demand and would indirectly help you in investing. 

The other option is to trade your assistance with a small PMC using the software.
