Advanced email serrvice provider

I'm going to create an email serrvice provider like icontaact, but with more features. I'm looking for someone who is interested in working long-term on a project like this, possibly a team of people. The program will have the following functionality - a billing system to bill users for monthly use - create a new account for each user - auto-responders that send out emails sequentially (eg day 1, day 3, day 7 etc) and also based on date fields (eg contact's birthday) and also 'other' dates like the day before hallooween - auto-responders are able to not just send email, but also things like fax, text message, letters/postcards, tasks etc - shopping cart so users can allow their end users to purchase products - affiliate system - users can create groups of contacts - trigger-based rules, so that for example if someone clicks a link, or has a field changed in their account (for example), then a rule can trigger another event to occur - task management system that picks up tasks from sequences and provides further tasks The first part is to define this job in more detail. Can you please reply with: a) If you have worked on this type of job before and what specifically you have done b) Your thoughts on the best way to move forward to define the project Ultimately, a quote to define the job, but we may need to converse a bit before we do this.
