Where to start with guidance and then drilling down what my personal potential is?

If you are using a lawyer, reach out to him/her to ask these questions as you could get yourself in trouble and may have to send a new NTQ.Also, specify to the resident that you need to have money order/certified check in hand by the date or eviction is continuing.  

At this stage, I hope to have enough experience, and the network to be able to accurately estimate total expenses, allowing me to move towards bigger projects with bigger potential gains.Any advice on ways I can move forward with my goals?

Do you happen to know a reputable lawyer I can consult with? 

That said I would definitely consult with both a lawyer and a CPA before making a decision. 

Any recommendations for lawyer or a reasonably priced debt collector to assist in collecting the debt ?

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

For off market, make sure you have a lawyer check the contact.
