Where can I get proxies for my purpose?

Hi everyone
I promote my websites on Facebook groups
The problem is I can't use single account for more than 30 posts a day, so I need multimple accounts..
So far I used add-ons for Google Chrome, but it doesn't working for me anymore because I have used the same proxies many times..
so Facebook doesn't allow me to open many accounts from the same proxy
What I need is new proxies everyday, where I can find such a thing ?
I tried proxies from "hidemyass" but they're not working for me for some reason, or working very slow S:
I don't mind to pay $5-10 a month, but I need a lot of proxies
Can anyone help me where I get proxies for my purpose?
Thanks

Can anyone help me please?

Have you tried using free elite proxies? If not then try it.

Here you can get the free elite proxies: http://gatherproxy.com/embed/?t=Elite

Go on buyproxies.org and purchase some dedicated proxies.

Search for my name on here - I released a script that will install elite squid proxies onto a VPS you own using all IP addresses. Instant proxies

Use the search button, i added some free proxies on a thread.
