Develop secure members area with online finance calculators and surveys

Phase 1: We need 6 basic calculators, which can be accessed publicly by any user. Develop the same online finance calculators as on this page: [login to view URL] They need to work exactly the same, but look slightly different. *These can be developed in PHP, Javascript etc. As long as they'll be compatible with a Linux server running PHP5 and MYSQL. Phase 2: As well, a more complex 'budget sheet' set of 11 calculators needs to be developed. Each calculator should be stored for later access and review by logged in members. Each calculator could work a bit like this one: [login to view URL] This is another similar example: [login to view URL] So there will need to be a members area to house this budget sheet set of 11 calculators, which means users can save their results and return later to view and edit their data. This should also integrate into a Wordpress site, so the logins users use to access the members area allow them to work on the budget sheet and surveys, as well as other Wordpress functional areas/plugins like forums and email list. The Wordpress site is already built and configured. I will provide Admin level access, FTP access, and can help with any other set up items for the database etc. Phase 3: 3 single-page user surveys with specific questions also needs to be included in the system. Results display in the user's own member's area 'budget summary'. They should also be able to go back and edit and save their answers in the surveys. Please message with any questions.
