Harn Gold

I do not see a Harn gold character sheet.. Is there any plan to add one to the list?

Hi Lord Enforcer,  Most character sheets are community created. There is a thread here  to ask for character sheets. People who feel like contributing to creating character sheets will go through those requests to make one.  Alternately, Roll20 may do a game's character sheet if it is popular or the publisher commissions Roll20 to do so. Finally, you might try contacting the publisher of the game to ask them to do so. 

Just FYI, there's a new edition of Harnmaster Gold coming this year called Harnmaster Kethira. I believe there's a good chance of getting a character sheet for that (down the line), but of course that's not going to help you right now nor with HM Gold.
