How to find someone who can design/edit SVG files?
I want to make some portable display stands and recently found out my local library has a laser cutter I can use! I thought this would be great because if I can find a file I like I can just laser cut the parts there myself. So I found some SVG files on Etsy of a stand that I like but when I asked the person to edit the file for me for my dimensions (of which I will pay for) they said they can't do it. (I suspect for some of them probably don't know how to do it and are reselling other files but I don't know for sure...)
Anyways, my question is... How can I find someone to hire who can create or edit SVG files for these display stands who understands what works and what doesn't? Allowing me to laser cut myself at the library. I don't know where to even start looking to find a person and thought this would be a good place to start asking.
