Can I represent him?

What you are describing is a "dual agent" role, where the agent represents both buyer and seller.

Quote from @Alba Cheung: i need some referrer for eviction lawyer in Fulton county. 

If the Broker was only representing the Seller then well you went un represented..

Coming from a family of lawyers the ones in my experience that make less than that are usually just not that motivated or are not that good at what they do.  

It's not worth hiring a lawyer but as you suggested, small claims court may be an option IF you hired them in your personal capacity OR if your jurisdiction allows LLC owners to go to small claims and represent the LLC in court (many, most?

.: The PM represents you.

My question is can anyone point in the direction of someone who could represent me in this matter maybe a lawyer or attorney, or someone who knows the fire code and who can be clear and concise on what I need.

That being said, lawyers aren't lenders, but they sometimes think they know everything.

The new ground lease and capital improvements represent the interest in real property you do not already own (and that is being created through this transaction).
