>Not sure this is totally on-topic, but I am thinking/hoping that someone will have some feedback on this nevertheless. The short story is that I am involved with a small (400 member) non-profit club who currently tracks annual membership renewal, etc. using desktop apps like Excel and Access. We'd like to move to a web-based solution that provides features such as the following.
>
>- Integration with our existing website, which is hosted on a shared, Microsoft server.
>- Allow for new members to join and existing members to renew their membership.
>- Paypal support for memberships and membership renewals
>- Automatic emails to members when their membership is about to expire
>- The usual, member (user) driven name, address, etc. maintenance.
>- etc.
>
>Additionally, we always seem to have a project or two that requires much of the information maintained in our membership database, so easy access to the membership data for querying and/or extracting to other formats is needed.
>
>I know the above is general, and feel free to ask questions. That said, I didn't want to bore anyone with countless details.

>Since we are non-profit (and small) free or very low cost solutions are preferable.

>Any ideas or recommendations are greatly appreciated.

Using Paypal infrastructure to process payments is a good way to go and fast. Basically, as oppose to other credit card payment gateways, PayPal doesn't charge setup fees and you would not have to purchase a SSL certificate. However, you have to redirect the client to PayPal site to make the payment. You can adjust that page however to obtain a look and feel similar to your Web site. Many users do not want to be redirected to another site when comes time to make a payment as they wouldn't feel secure. But, for such a site, based also on a non-profil infrastructure, this would be something to consider.

As for the rest, well, it falls in consulting business. So, it all depends on whoever will quote on that one. Some may have special quoting structure in such a case. But, usually, they would charge there regular rate. You might also find an off the shell product that you could use and, maybe have it for free. But, in overall, whatever is free or low cost expense, usually delivers the same in return.
