In terms of registered agents in general, you can just hire a professional service to take care of it.

I was thinking of hiring AdWord Nerds to help with SEO and paid ads.

The best opportunity you will have to replacing out-dated systems (plumbing, electrical, HVAC) and improve the energy efficiency of the building envelope (air sealing, insulation, fenestration) is before a building is placed into service.  

There’s a 3bd/2ba home listed at $83,500 built in 1949 with central air/heat if I put 20% down , will I be able to rent it out ASAP ?

(Like air BNB).

Right now I'm building a new rental and hired a GC.

I need to hire a structural engineer to shed some light on what caused what and how to go about fixing this.

What do you think about it? If im doing a no money down deal( i dont need a realtor)Is it possible to hire a realtor as consultantSo i can access to the MLS ?

The outside of the house looks well maintained and cared for, not in obvious distress. perhaps there are foundation issues, but it's block and beam so I'm not entirely sure how difficult that is to fix. it has window units but lists as having central air, possibly it's broken?

We bought an Enerzen Commercial 6000 mg 03 Air Purifier Deodorizer.
