Design and build members website, seo work initial and ongoing

I want to launch a website. It will be a members site and will feature: 1. Landing page will be a log in page. Clients must register by submitting their email address to get a user name and password in order to get access to the site. 2. The site will be about 6 or 7 pages which will promote our product and invite clients to apply for membership, with a monthly fee payable. I require the website to be designed and built, and it must incoprporate aweber or similar to manage the client database, both for subscribers and registered users. Site should be on latest word press platform and be SEO friendly. Ongoing work will be to get us top position on google results - the keywords are in a specialised area, and are not ultra-competitive. Your quote should include time and cost estimates for; 1. Design and build of the site, including database management, monthly charging of clients and easy to use content management system. 2. SEO work to get us in top google position and keep us there. Successful completion of this project will result in further work - we have other sites in the pipeline and there will be ongoing work available.
