Now I know you can get a deal for "free" using a few different methods.

Additionally, another method to limit liability is to keep refinancing to have equity in the property be very minimal.

Most of my research has been geared toward the BRRRR method.

Since the biggest risk in the BRRR method is appraising a rehab, it makes sense to find a job that does just that.

Electrical, plumbing...probably best left to professionals.As for managing your property, by all means do it yourself. 

As a new investor, what is a good company to use for private lending methods?

Look, we have experience with the methods that were listed in the OP. 

The method I've been using is looking for new construction, specifically of grocery stores (Follow the Walmarts haha) or housing developments.

I would get a second bid from another plumbing company.

Hard to say without knowing how much rehab is needed but as a general rule of thumb: If ARV is lower than 250k: 55% ARV minus repairs If ARV is higher than 250k: 70% ARV minus repairsOf course this method may vary depending of the market but it’s a start ;) Good luck !
