$49 a month for a VPS is heaps, take a look at this site http://www.lowendbox.com/ you can find plenty of VPS providers there that would be suitable for as little as $5 a month.
I have used http://www.intovps.com/ before for a proxy and they were great, here is a really easy tutorial on setting up a private proxy http://www.vo1dmain.info/how-to-configur...oxy-on-vps
I'm assuming you have a legitimate use for your proxy as I do, otherwise you will have to be mindful of your VPS providers terms of service.
