Hello,
I found this message board while doing some research for one of my customers. I am an authorised reseller of Authorize.net, and of low cost credit card processing. Please let me know if it is inappropriate to promote my business though this forum. I offer authorizenet services with $0 set up, and $5 per month. I work with hundreds of campanies large and small and can provide many references if needed. I also work with web developers and marketing companies and help them set up their customers.
Please send me a reply if you would like more info, I would be happy to discuss it by phone as well, I am east coast.
Thank you
