I have used rub ratings.com successfully a few times but, to be honest, it was a lot of work sorting through the bullshit ads to find and connect with a real provider that delivered the services promised in the ad. Most of the ads that I responded to were either fake, a scam of some sort or the provider didn't fulfill the promises made in their ad. If you are willing and have the time, you can find what you are looking for on that site. But, like most of the hassles of this hobby, it takes time, work and diligence to no get hustled. YMMV, but that has been my experience over and over whenever I try to find alternatives to your runoff the mill, storefront AMPs.
