If you had to hire an attorney on your own to advise you on this stuff, that makes the self-managing rather expensive. 

Quote from @Kaleb Johnson: Quote from @Brandon Vukelich: @Kaleb Johnson if you are serious about wholesaling, it is highly recommended that you hire a real estate attorney in your state to help you draft the docs you need, applicable in your state.

I did hire a VA to cold call like 12,000 people and it was useless.

The first one to hire would be the accountant.

I guess if you could find a virtual bookkeeper willing to do the work for $50/month you could hire them.

Do I need to hire a property management company to obtain the rental license? 

I understand they need to turn a profit and pay for overhead, but the minimum they should pay a cold caller is $5.When I hired my first cold callers, I outsourced it to an agency, then I brought it in house.

Costs a fraction of the funds compared to hiring a cold call agency.

As far as hiring the other trades, this can be difficult from a distance, who is helping locally?

Hire a loan servicer - plenty of discussion and recommendation on BP on this topic and some recommendations for servicing companies
