Excel, VBA & Macros

Hi, We have an Excel databases First Name, Last Name, email, company, address, mobile and cell numbers etc We require: Sheet 1 Remove any entry that has a number in Cell K - Only want to be left with entries that have no mobile number Sheet 2 1. If Cell A, B and then either C, D, E, F or J are the same as entries within 4 up or 4 down then remove the entry if no number in K [login to view URL] Cell A & B and either D, E,F or J are the same as entries within 4 up or 4 down then remove the line entry if cell C has @gmail, @yahoo, @ymail, @hotmail, @aol, @live, @msn, @outlook, @comcast, @att or @cox in the email address [login to view URL] finally remove all entries that have a number in Cell K - I only want the ones with no mobile number left... But I need steps 1 & 2 done first to get rid of as many duplicate people as possible. [login to view URL] that process then if in sheet 2 there is only 1 entry with the same name in column A & B can we move that entry back to sheet 1 I believe we need someone who is an expert in MS Excel and who knows VBA or Macros in MS Excel. We require this work to be completed within 4 hours
