wordpress pluging development

Briefly, My current personal blog ([login to view URL]) will be based on subscription. And invitation codes will be distrubuted to people who are interested. This website is in turkish language but coder doesn't have to worry about the translation part as i'll be taking care of the translation part myself. Just want plugin to be developed in english. To do list: I want users to login from clicking a pull-down panel at the top of the website.. You should have already seen such swinging pull-down tags or ropes hanging at the top of the page. When users clich that a panel drops down.. This would create a simple but effective interaciton. Users will register manually by themselves, not by admins. New users will enter a invitation code(password) from the pulldown panel. If it is correct, they will be directed to a full registering page to choose a username(and entering some other infos). If the pass is wrong, by using ajax, "pls enter the right a password" text will be presented at the bottom of the related submit box. Also I want to "anchor" this invitation code to users' facebook account to prevent sharing of the same code. ( or do you know any other method ?) I need a single sidebar (like the current theme has), but this sidebar (in a way) will function as a control panel for users: All the posts titles will be presented at the sidebar, but some would be faded out according to to user-group he/she belongs to. Some groups are not allowed to see all the posts. There will be 3 groups totally. (wp-sentry is perfect for this feature) Home page will be composed of 1 post which will explain the content& other things related with my blog. A mini simple profile box is necessary. This will include the a short welcome message space, users name, subscription type and a upgrade box. If a user wants to upgrade/switch his subscription , he will just directly enter the code and press the submit button. Upon verifying the code, he will access to posts that was not available to him before. I have found plugins related with those issues that would definately easy your job; Plugin names DBD Login Style & BM Custom Login Page Restrict Limit Login Attempts Facebook comments Register Plus wp-invites peters login redirects wp-sentry The site is in turkish language but coder doesn't have to worry about the translation part as i'll be taking care of the translation part myself. Just want wp plugin developed in english within the next 7 days after i accept the bid.
