compare list of 1000 names to list of 59k names

I need to compare two lists of client names. One list has 59k names to be compared to second list of 1000 names.
The list of 59k are listed in column D and the other list is in Column E. I tried conditional formatting but unfortunately some of the names are slightly different I.e. fair point communications vs fair point communications inc. I was trying to put in v lookup with a trim function but it didn't seem to be working. Any help would be much appreciated. Thank you
