Hello, I want to buy a VPS with basic configuration with around 3-5 GB of disk space and unlimited bandwidth on which I will host a proxy and a forum. Price should be cheap as I am looking for an yearly payment option, but before I pay for an year I would like to test the service for a few days or for first month on payment. If you can offer good service for cheap price please let me know. Thank you.
ShopaServer.com is the host you are looking for , they offer lots of bandwidth in tera bytes with 1 Gps port, very very few hosts offer terabytes of bandwidth at 1 Gps port, since you are hosting proxy it would be excellent for performance, the price is around $15 per month but I think you ll get some good discount on yearly payments. good luck!
Try looking at http://www.ajkservers.co.ul , you can have both linux and windows from one place. I have also tried FDCservers and they were very good.
I know happy-hosting.com is the best company in terms of VPS and I'd recommend to use them to meet your needs, the OP.
thank you everybody for your suggestions but I am actually looking for a VPS with "UNLIMITED BANDWIDTH", None of the host suggested by you provide unlimited bandwidth usage.
