I don’t think that $2500 is a good price. It actually seems like a terrible price. What’s your plan? Make 200 yoyos just for yourself? It definitely seems like you’re jumping way ahead in the process, you need to do some real research.
I did all this for the first time in 2018, which you can read about here: Yoyo CAD & Prototyping Adventures
My initial foray into yoyo design took a couple months of CAD practice and about $650 of money invested.
If you were looking to make your own cool thing, you can hire a reputable yoyo designer who can walk you through the process.
