Also I will need online support on the website on made changes for 6 months. Source code should be unencrypted so that we can make changes, if we need so [when you will not be available]. For future development we will pay separately. Payment Terms: 1. 25% 1st Milestone after front end & User / travelers End Development: 2. 50% 2nd Milestone after Admin Panel development 3. Remaining once the application will be tested and installed on our server [Without any bug] so please excuse us, if you are not satisfied with all our mentioned terms. Happy Bidding
