VST vb6 existing priority developed software

The VST Fuel Management software is privately used by the customer's that are using the VST Fuel Management system for tracking dispensed fuels (diesel, gasoline, etc.). The VST software is built on a vb6 platform using Microsoft access for the database and excel for the reporting, etc. The VST software has been in use (and still is) for several years. I'm looking for someone who can log in to my computer and talk about what I need to have done. The reason I'm reaching out is that the software guy that built most of this program for me has dead. There are a few items that he was working on that didn't get completed.
