I've had great luck just getting people to do stuff on Upwork for Excel. Tons of people that have experience building all sorts of excel programs and macros. The skill is called "VBA".
Depending on what you are using it for I'd really encourage just going along yourself and trying to figure it out. When you need to change something you will be way better off. If you get stuck just go join an excel forum with a female handle and get great answers to all your excel questions.
Excel is awesome BTW, did you know it can even scrap data from the web? You can write an excel VBA program that will go open other excel files in a folder, format the data and ingest it all nice and neat.
