This is a fairly simple project for a middle level experienced person. We need a single page web portal which reads incoming message from gtalk/hangout as soon as it arrives, saves the sender's name, date/time of message and the message itself in any database (MSACCESS/MYSQL/MSSSQL) and sends back a reply message as acknowlegment. No designing required. Just read the message, store in database and send back a reply. The communication needs to be in realtime and any number of users can be attached for incoming/outgoing messages. You may use your own gtalk login credentials for testing.
Make sure, you provide only plain C# code without using any dll/references/hidden code. Code should be neat and clean and straight forward.
To ensure that our requirement can be fulfilled, a little sample code will be required for testing, which may just read the message and sender's identity.
Please read the details carefully and bid only if you can do the job perfectly.
