Maybe join the future and stop doing it the old way. Nobody hosts their own web sites anymore. Even huge companies outsource this function.
For $250 you should be able to lease server space for a fairly long time. Since it appears you have low traffic rates if you can host it on a raspberry it should be very inexpensive. I can't give a good recommendation since I was using vpn at high traffic rates.
Your best bet is going to be garage sales and maybe a local flee market. You can look on ebay but because shipping is going to be a lot I would look at laptops.
Walmart sells a number of brand new laptops for under $250.
I would still consider hosting
