Kat, welcome and look through the forum. There are several threads here where people have essentially stripped their trailers down to the frame and rebuilt them. So, it CAN be done DIY. However, it can be a big job that's intimidating to anyone who has no experience in this process.
If you want to get the trailer rebuilt professionally, you could take it to Midget RV in Bellville, OH:
https://hilotrailerparts.webs.com/. There used to be a place called J&R Repair in Butler that serviced HiLos, but I'm not finding them now.
Edit: J&R is now in Mt Vernon OH, as shown in the posts below, and they don't seem to have a webpage anymore.
