Data Extraction From yellow pages/others link

Hi, I need a freelancer to enter data onto an excel sheet. Quite simply I am in need of email, mobile number and addresses. I have two websites, directory websites which I need the data from. It will require you going onto each person/ business listed on that site and being forwarded to their website. From their website you will need to fill in as much detail as possible, i.e. email, mobile number & address. I need this project to be done as fast as possible and as accurately as possible. If inaccurate data is entered or there is lack of data overall then the project will be cancelled. Regards fhasan
