Permaculture designer in Mobile Alabama

I am wanting to hire a designer for rainwater catchment and grey water use.  Does anyone know if anyone like that in the lower Alabama area?  

I am wondering if you really need a permaculture designer for a water catchment system.

What is in your reasoning that one is needed?  Is there a design that integrated plants or gardens?

Do you need gutters or do you already have those?

What kind of roof do you have?  

What kind of greywater system do you want?

Maybe a little more information would help.

My home is on a slight slope and we get about 60-70 inches of rain per year, with 2 separate months that get very little rain, 2 that get a whole lot, then the rest spread out.  The moisture has caused damage to the joists and crawlspace as well as the subfloors.  I am encasing the crawlspace; will use it for storage.  In addition I need assistance planning and executing a way to assist the water to go around the foundation rather than sitting on it.  I also want to incorporate water storage, be it in tanks or in ponds, and also grey water use.  Thank you for your response!
