php and mysql changes part 2

I need a programmer to do the following tasks to an existing code: 1) allow to upload a 3 and 4 column CSV file containing specific headers into a mysql database. In the version with 4 columns (realemail) we will generate the necessary permutations and then match the results to the 4th column value. If there is a match, we will make save this to the database. The goal is to know that a domain uses a specific format. What's important is the format (i.e. [login to view URL]@[login to view URL]) and not the actual address 2) modify search function as well as CSV uploads so that it first checks the database to see if records exists. This will be done by using the first name, last name and domain columns. If a match exists then we will use the information already stored in the DB and will not launch the calculations/permutations MAX BID: $20
