Hi there, went through the description. We will be developing the application in PHP language as it is Open-Source & can be accessed from any browser with internet connection. We have developed few complicated web-apps & I will be interested to build this app for you. If you have any questions then do let me know. I'm very confident about this work & would like to express my interest to work for you. Please reply back with "Hi" so that I can share my experience. (Due to word limitation, I'm not able to do so in this message) - I look forward to working with you. :-)| No advance payment needed |
