Hi,
1 GB is not enough for public rleech , your vps will down rapidly.
Most famous providers don't check your vps content, unless you consume a lot of CPU.
So for 1 GB, you can only create private rleech, and you should know how to install it cause they'll not support you to install it (unless it is a rleech host).
For public rleech, i suggest you order dedicated server, so you get full CPU.
