Improve excel macro that sends 1) calendar invite and 2) standard email

I have a macro in excel that I use to send either 1) a calendar invite (standard .oft file) to a list of recipients, and another macro that sends text from a cell in excel to a list of recipients. The issue with the code (which does work), is that it does not keep the formatting of the .oft file for the calendar invite, nor the formatting of the text box in the emails it sends. So I am looking for a fix to the macro code to ensure formatting is retained in what is sent. Only people experienced in outlook at VBA please, I will not appoint anyone without experience. Budget is max $75 Thanks
