How to get this custom made from Etsy?

I found this ring online and I really want it, but in solid gold (not plated). The creator doesn’t do solid gold, so I thought about asking an Etsy ship owner to make it for me custom but I’ve been searching Etsy and I’m not sure how to find a shop that makes custom jewelry. Any tips??

I want to go through Etsy because I think it’ll be cheaper than Zales or some big chain. (And also to support a small business.)

* I tried putting custom ring in the search bar but it only gave me specific rings that you could customize with a name or something.
