Hi i am looking for shared hosting for proxy site. My budget is 10 $ and host with atleast 50 gb bandwidhth.
I highly doubt you will find a reliable and well-known host that will allow proxies on shared. If you do find a host that allows this, i'm sure things will be ok for a while but keep in mind there will be other sites just like yours hogging the CPU/RAM and evidently the server will sooner or later be overloaded. If I were you, I would go with a VPS package to avoid downfall issues and to maximize scalability.
When you're just starting out, VPS and Dedicated is a bit too much when it comes to balancing your budget. Check out DP's web hosting section, I have and see many individuals who are offering a reliable service for decent price with happy users. Hope this helps
