Hi,
For exclusive proxies you'll not find a service that gives you different ones per day.
As soon as you are offered that you know that the quality of the IPs is bad due to the high abuse on them.
Some of your options are:
* Signing up for proxylists, those are "free" proxies that are sent by email or downloaded on websites
- That's like the ones you are using now but a bit more "exclusive", less searching time required but same disadvantages
* Tor
- Free, usually very low speed, many IPs, very good anonymity
* Cloakfish
- Based on Tor but faster, geoips and specialized for the use as proxy for mass IP requirements
* Shared proxies
- often fast speed but also abused a lot
* Exclusive proxies (Private proxies)
- often fast speed, abused much less than shared ones
* VPNs
- I'd only use that if you're in china or a similar country
* stay away from russian/eastern offers, those are hacked computers
Each of those solutions come in various ways.
Not every exclusive proxy is fast as example, you'll have to dig into the offers
As last word: I'd suggest you to buy your solution from a BHW member with good reputation/history.
The proxy business can be very dirty, in worst case you're getting illegal access to hacked computers or your exclusive proxy turns out to be not so exclusive after all.
