Creating a paid membership site
I am trying to create a paid membership site where once users have paid they can gain access to a special section of my site with a unique username and password. In this section there will be special content, downloads and a discussion forum. Now here is my problem, I have looked at ccbill.com, probilling.com and ibill.com but I am not sure which would be the easiest to use and has the best customer support so I thought I'd ask if you guys have any experience with them? Also, I had a look at paypal options such as memberzip.com but I want to stay away from paypal because my customers will have to be papypal users and this is limiting my audience which I feel will decrease sales.
I am trying to keep my initial costs down so paid services are not really an option (unless there is no other choice).
Can anyone help or give me some advice, even a link to a good resource would do. Thanks in advance for any help you can give me!
