GC, Architect, Expediter recommendations in Atlanta

Hello Atlanta!

Considering buying a 3/2, 2/2, 2/1 type of older house and hiring an architect and GC to make it a 5/3 with a garage in east atlanta.

Has anyone done this and have any referrals? Share your experience?

Our plan would be to buy this house (if possible, move in) and hire an architect/gc etc. Get permits. Then move out for however long it takes to complete the work.

I understand that now might not be the best time to try this due to labor/material demand. 

I understand the impacts of cash/financing.  Like i can't buy a 3/2 on a conventional loan and then start tearing it down.  We have the income/funds/assets to make this happen.  

We're looking at doing this in East Lake/Kirkwood/Oakhurst/Winona Park area.  

Thanks!
