Hi there

I'm not a professional so seeking some advice please - I've developed a basic Dreamweaver website (on a voluntary basis) for a sporting organisation. Now that I'd like to step away from this work the organisation would like to find a one-off cost website package, without advertising. They are happy to pay an up-front off-the-shelf cost but not on-going fees.

They are hoping to find a web-package that will enable functionality beyond my abilities, as follow:

In context editing (so customer can easily edit webpages himself)
Database link with login for interested parties to register
Email newsletter send to registered parties
E-commerce

Would anyone have some knowledge of any such packages please?

Many thanks :-)
