J2ME mobile messanger for Joomla

I need a Custom OPEN SOURCE Mobile Messenger Application that will be integrated with the Joomla community builder : Jomsocial ([login to view URL]) I am looking at creating something similar to BBJSOCIAL Visit <[login to view URL]> to see the features and the demo The Improvements I will need are: 1. The Mobile messenger Should be J2ME so It can run on Nokia Phones too 2. A Chatting and Messaging system should be incorporated so logged in users can chat with their online friends 3. The invite friend feature should be more viral. Users should be able to access their phone book and invite (via SMS) their contacts to join the network. ( The message sent and the http api to use should be configurable from the admin) 4. The Title should be the same with the title of the joomla site it is used on. (called from the joomla database) 5. Facebook Connect: The mobile application facebook connect will enable the members to connect the app to their facebook.(Done one time) When connected, Members can see and chat with all their friends (Both Friends on the jomsocial site and their facebook friends). The package should work on any of my joomla installations independently. (All my domains... I intend to use it on more than one domain i.e different joomla installations) Jomsocial is not encrypted and its open source. You may tweak the files of jomsocial or joomla to fit the project. The application design should be simple, sleek and web 2.0 compliant. Please use a technology that will make the application load very very very fast. (Low bandwidth) No encryption, will need all source files fully documented Timeline: The App Should be ready in about 2 weeks Budget: If you can do this (and fast), Give me your quotation. I have a shoe string budget. Looking at around $500 or less. payment will be through escrow Thank You Bids from only experienced mobile app developers and Please there is no need to bid if you are not very knowledgeable about the Joomla frame work and jomsocial
