Excel/Access consultant?

Yeah, I know we should not be using things like this, but we’ve got a really complicated Excel spreadsheet linked to an access database that I really have no idea what I’m doing with and quite frankly don’t care to spend the time to learn as it’s not really a profitable thing to put on a résumé. Does anyone have any successful stories in working with Excel or Microsoft access consultants? I know Microsoft themselves are probably a lost cause. What’s funny is we have the guy here who wrote all of this and he can’t figure it out either. Beyond my local MSP. I have no idea where to even look, luckily, this can be done remotely, of course.
