Commerce Web Site

I am looking for a developer with experience setting up a relatively simple commerce addition to an existing web site. The site needs to be set up for secure login and to accept regular subscription payments. I would like to use PayPal's Web Site Payments Standard. The customer should not need to have a Paypal account to sign up as a subscriber. The subscriber should be able to use Paypal or major credit cards accepted by Paypal as payment methods. The work should involve handling exceptions and generating the appropriate correspondences or alerts to subscribers using Acajoom's email management system. The work should include any and all education on how to manage the process and should be able to handle exceptions such as cancelled credit cards, rejection of credit cards, automated cancellation for the subscriber, etc, as well as similar capabilities for me to override and manage subscriptions as the site owner. The project needs scoped. Thanks in advance. ## Deliverables There should be educational deliverables and training of how to manage the site and its functions.
