Anonymous sms for dating site

Hi, I have a site [login to view URL] and want to launch a dating section. My site is in a LAMP environment. MySQL and PHP is the code i want to be used. We use vBulletin forums ([login to view URL]) and vBPortal ([login to view URL]) software. I don't want to just launch dating where people can search on fields and place posts where they say that they are looking for a girl or a boy. I want something extra. That's how i came up with the idea that people must be able to put their mobile-number in their profile. the number shouldn't be displayed. Just a button with the text 'sms-this-person'! When a person clicks on that button a small pop-up screen should be displayed where the sender can send the person a message. He should be just having to write the message. The rest should be coded so that nor the sender nor the receiver pays anything. BUT, the possibility of making it eventually a paid service should be also coded, so it has to be flexible. It should be fully compatible with our own MySQL databases. So it should use our user-table and cookies/sessions etc.. So that it can be integrated. IT MUST BE FULLY WEB-BASED. I want to be able to assign users two kinds of sms-credits. The ones that never expire and sms-credits that expire each period(which i should be able to change; for instance every 24 hours the credits which are not used get flushed). I want also to be able to assign an amount of sms-credits automatically daily(sms-credits that expire after an amount of time) and an amount(bonus) which i can assign users manually(sms-credits that never expire. So i should be able to determin the amounts. Furthermore i want all sms-messages sent through this app to be stored in my database. If you need more info, please contact me on the emailaddress i provided. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform LAMP
