townhome courtyard drainage examined

I am looking for a professional to examine the drainage system of my townhome courtyard. The courtyard measures under 500 square feet, and I am currently experiencing regular flooding. I would like the project to be completed within a month, depending on what the findings show. The successful freelancer must have experience in drainage design and installation, and must comply with any applicable local building code regulations. I look forward to observing the different quotes and estimates for this project, as well as seeing a plan for the proposed improvement.

I just need a qoute for someone to examine the situation and give me their findings and solutions in writing to take to the HOA.
