I've hired a company for this credit issue but just wanted to see if there are any other options out there 

If it isn't insanely costly - you might want to hire a property management company. 

I am building business credit and I got a phone call from a rep from D&B telling me that I need to pay $499 to finish my profile with them..I already have a D&B #, so why do I have to pay to complete a profile?

I would think they should know if they double cross you like that their rep is going down.  

Your already living there, dont hire someone else to do the work and cut in your profits.

Elliot I am looking for an Attorney who is preferably a CPA and an investor to hire.  

Here in LA we have dual agency, but in TX I understand you can't be repped by an agent on both sides.  

I read something about hiring a loan office with a license or something to take over?

The lack of regulation in the area of hard money has opened it up to con artists and predators, another reason hard money has earned such a bad rep.

As someone looking to hire a contractor.... it would be a red flag to me that you would be asking for this downpayment... then again, a 6 figure project may not be that big of a deal?
