I use Sign Search and have been with them for around 5 years. The sales that i have made far outweighs the cost of Sign Search. However if you looking for business from local stores/retail i get no business from Sign Search. The only clients I get are national sign companies looking for installers and service work. Without Sign Search i think i would be out of business. They are my only advertising. I would recomend them. I am in Southern California.
