I decided to splurge

and spend 99 cents to get 10 proxies instead of waiting for a free invitation code. I would really appreciate some advice because after a week of googling and reading as much as I can and trying about 30 free proxy sites, I am at a loss.
I tried 5 of my 10 proxies and none of them work for
me. They are probably perfectly functioning IPs (I am sure they are fine) but they are not working for my application.
I would be happy to send my 10 proxies (which I assume will work for other applications) to anyone who can give me the advice I need. If that's not a fair trade (since I only paid 99 cents for them) that's okay too.
Here's what I am looking for without breaking the bank.
A bunch of proxies that will work on ONE site I am on every day. 50 is a good number for me.
Today I 'killed' all 10 private proxies that I bought through BHW that did work very well, but I didn't work as hard as I could have today to at least 'save' my home IP for tomorrow.
I guess my thoughts are - those proxies are perfectly good still on EVERY other site, and after a 24 or 48 hour ban, they will work again for me too, so using private proxies seems like a bit of a waste.
For the site I am on, I need to access ' https ' pages.
I assume that is the reason the free proxies do not work for me.
Speed is important, but if others use the same proxies as me that's mostly okay.
My thought is to buy up to 100 private proxies, use up 50 in a day, wait 24 hours to be able to reuse them (after my IP block is lifted) and use the other 50 the next day. And keep rotating them. That would work unless I was blocked for more than 24 hours which can happen too. I just feel that there must be better alternatives out there but my research hasn't led me too them.
I can't PM yet, so to anyone who chooses to answer me, if you would like my 10 proxies, IM me your email address and they are yours. THANK YOU
