Search the Web for Phone repair shops in USA``

I am looking for someone to research and create an excel data sheet of mobile repair shops in the USA. The database must include information of 20 thousand shops. I aleady have a datasheet and your job also will be to make sure that the 20 thousand shops are not included in the data sheet I already have by making sure the phone numbers of the shops you want to add is not already in the datasheet I gave you. If you read this description please start with READ. Once awarded, I will supply you with a spread sheet I already have and you should use it as a template for the new data you will be adding. I need you to proof read before submitting to me because if there is a 5% or more error margin in data when we review it, YOU WILL NOT BE PAID. Data errors will be something like if a shop you included does not offer mobile repair services or it is permanently closed or the phone number is wrong! *Also, I don't want are any shop that has any of these keywords in the shop name: ATT, AT&T, SPRINT, TMOBILE, T-MOBILE, METROPCS, METRO PCS, VERIZON, US CELLULAR, Boost Mobile, Boostmobile, Bestbuy, Best Buy, You can use Yellowpages, Google Maps, and any other sourse to find these 20000 shops
