You need to look at what other LL's in your market do and follow that custom.

I have an excellent work ethic and have great customer/client relationships and satisfaction.

I'm a realtor in Houston, TX. I own 2 lots, side by side, in a very desirable area of town.  My husband & I want to contract with a builder to build us a home on one of the lots, and a 2nd home on the lot next doo...

You will have to learn your customer acquisition cost however.

I also had a huge culture shock in two directions 1) the revelation that mobile home parks were nothing like I had learned about on TV (which showed them in a negative light) and 2) the knowledge that the demand for affordable housing was huge, as I would get sometimes ten calls a day with customers looking for a cheaper place to live. 

.#2 they always have stories about how they used to be a big time hot shot building new big $$$ custom houses until "insert excuse".

The transfer station, however, is closed to the general public (besides commercial customers) .

Real Estate sales will definitely slow down for the next ~10 months while employers evaluate how to get businesses back to capacity, slowly hire back employees and customers/clients slowly start to trust the economy enough to start spending again. 

Atlanta is a major market, and that means major competition and as you said your a newbie so if you can't beat them, make them your customer and profit from them. 

If the contractor pricing comes in higher, then a discussion will need to occur between the customer, consultant, and contractor.
