I have 8-10 thousand contact for a yacht sales company that needs importing and entry into excel spreadsheet format, so i can send out mass e-mails without it being considered spam or junk and also i need to be able to cross reference the contacts for what they are intreseted in buying. i.e i want to be able to type in 50ft or 100ft and all the contacts and their respective details will come up. i have all of these and it's a mess i need someone to clean this database and purge them. i need this done in excel spreadsheet. I also need to know how long it would take.
