Make Letterhead Text in Margin Editable

I have a current .DOC letterhead. The company staff's names are all listed in the left margin column. The current staff list is a static jpeg image. The client has requested this be changed to a simple editable text format, so that they can can/update staff text information in the future. Currently there is also one staff member's name which is misspelled and needs to be updated. Any editing by the successful freelancer must keep as accurately as possible the same grey font colour, and format so that when opened on any computers, the left margin staff names font colour and size always remain the same. The other functionality of the .DOC, mainly the main body section where staff can type a full 1st page of text and subsequent new pages are created as they type past page 1 must not be affected in any way. I have added the .DOC to be edited. I require this simple job to be completed as soon as possible, the fee is $20US, thanks.
