Sage 100 developer to move my custom code to current build of Sage 100 -- 3

I'm looking for a Sage 100 developer to help me move my custom code from an older version to the current version. I don't need any customization or custom report writing and I have not specified if I require access to the source code or IT personnel. I'm expecting the freelancer to offer expertise in the process of ensuring that my custom code works on the current build of Sage 100.
