VBA, Mail merge records from Excel to Word

I need some help with merging data from a spreadsheet to Word. I have been using mailmerge but I need multiple records from Column4 where the items in Columns1,2 and 3 are the same. I can do basic mailmerge and so now I need some form of configuration to bring in data from the next record when my conditions are met. See attached spreadsheet. I need this. <> <> # <> <> <> <> <> <> <> <> The next file/page will occur when the above is populated, and then the same sequence will occur again. I need to understand how this is done as well. This is a tiny job for the right person, hence I will agree a reasonable fixed price to the person who can show me what to do. I can already nearly do it so a VBA programmer won't take long. Thanks Mark
