This might help.
All subdivisions and comercial projects have to be reviewed by the county.
If you vist the county office and ask real nice the will give a list of all approved projects in a certain period ...like a 3 month period. Give them a time frame.
It will have the project ... the attorney....lot block...address...owner....all the cool info.
After a while all you have to do is call and have them email you the list.
You take the list to the town ask to see the plans and bamm you know what you are working with.
If it is a a gas station or office do some proposals for them and see if you can come up with something that stikes them.
I would do this in the winter when you have the extra time.
