VBA to format bold a concatenated string

Similar to this thread - http://www.excelforum.com/excel-gene...ted-items.html

All I need to do is something similar BUT only one item is to be bold. But that bold item will change in charater length, so counting where to begin the bold (like shown above = 58 character) doesnt work for me. I need to join (3) items where the second itme is the one to be bold and changes.

Problem:
A flat fee of $11,750.00 is agreed upon for the delivery of the services.

This dollar amount changes any where from $1.00 to $999,999.00

Results to be placed in A155.

THANK YOU IN ADVANCE!
