we totally cant help you, we dont have enough info. How much are you spending on advertising? where (exactly) is your location? how much drive by do you get? what kind of advertising are you doing? Without this info anyone helping would be totally guessing. Do not use the numbers Im about to give you as a base line as I was in a different area. In my first year in Allen Tx we spent $75,000 on marketing (radio, I wanted billboards) and were 5 min off of the interstate and 50 min from Dallas.
we saw 9,000 people.
