I have a site near completion and have a need for someone to work for approximately one month, perhaps longer on the following:
1) Testing: Test all forms, pages, searches, etc and make sure that all the code is fast and secure. There are several large queries and a couple of submission forms that need validation.
2) Some of the existing forms and pages will require AJAX to increase the appeal of the site.
3) There is a function for a js "Digg" like function required. There has been no work done on the js function so it will be a fresh start in this area.
4) Newsletters: There will be multiple query based newsletters that need to be constructed.
5) Cron jobs are required to send the newsletters and do periodic maintenance on the database.
This is a summary, the hours and work load may vary.
