So, I am back where I started and have a W2 again (in my own biz) and we have a small team managing the rentals, I only get involved with buying and with bigger construction issues. 

By negotiating 20-35% discounts, we managed to achieve cap rates between 9% and 14%.I've also started managing properties for three of these clients, listing their rentals and ensuring everything runs smoothly.

I think many that start wholesaling have very little knowledge in real estate.

I'm starting my first campaign since getting my license and am curious to hear what works for others. 

What are the essential first steps I should take to start this business from scratch?

We have a 2 year lease with our first tenant starting soon. 

Where do I start?

I was able to save my clients a lot of money through aggressive and strategic negotiations.

Or save for another home downpayment? 

I'd start by searching the forums here for "section 8" related threads.
