Client Side Instant Messaging Blocker and Parser

Im a student that need this application for demonstrating: A client side application that will recieve all Instant messages that are recevies on the computer from all type of IM applications (MSN Messenger, ICQ, Jabber , Skype). the application will block those messages from appearing on the Instant Messages application dialog forms and will send thos messages to an external server I have built. the application will receive messages from my server and will send them to the IM client apllication for presenting (only the messages that have been receive from my server). for example in case I have a friend who I am talking to through MSNm messenger and he wrote me "Hi Noa" this message will not appear on my Messenger application on my computer - instead it will be received by the application I want you to write and this application will send the msg to my server. after some time my server will send a new message back (for example : " hi Noa :-) " and only this msg will appear on my MSN Messenger application. I am a student with a short deadline so please only reasnoable prices and short time to deliver will be considered. only bidders with experience in the field that knows how to do it and have experience with it shoul bid. Thanks, Noa.
