Joomla & E-Commerce Integration Site

I have a client who is a non-profit organization who requires a new Website. They have an existing site with a membership directory, calendar, events management area that is all manually completed. They have several forms that they require users to print using a PDF for them to submit. They want to make this an attractive 2009 type Website where there users can login and maintain their user profiles, sign up for continuting education courses, pay for the yearly dues, and also be notified regarding events (membership, newsletter etc). They need to be able to easily integrate organization banners/images. They would like to use a COTS tool. The intended Web host will be IX Webhosting.? The organization is willing to use Google's Checkout Solution or Paypal Solutions for e-Commerce if development of an e-Commerce cart is difficult with a package such as Mambo or Joomla. Additionally, they will require a custom design.? I will be documenting all the requirements for you and work with you to achieve the end objective. ## Deliverables I will provide the Website to all individuals I am considering final candidates so that they can provide full scope and details of work upon me reviewing credentials.
