Data Entry Project with good Searching skill

I need data entered into CSV format from some of the popular UK online business directories. I already have a database and no duplicate entries are to be included. Most important field is Email ID. I will provide 1 site from where data has to be taken out. Some Missing Website & Email IDs have to be searched so you need good searching skill. There is 1 category only. Data must include: Business Name Category Address (line 1) Address (line 2) Town Postcode Telephone URL Email All records MUST have all this information. No duplicate listings. I already have a database so you can check & avoid duplicate listing. I will PM categories if needed, there are around 1700 companies shown on yellow pages. If the record already exists please do not add another. I will pay $25 for half of the work assuming that half of the records exist in my CSV database and send final payment when it is clear how many records were added. IF you did find all of them the value of the project would be $45.
