This is a very custom module i need for my online shop. We prefer Indian Developer to do this project.
1. Need City Dropdown [configured from Admin area] in Checkout page.
2. In Checkout page, When State will change, the City Dropdown will repopulate by AJAX with the state-city mapping
3. Sale from any Country [ billing address] but ship to INDIA [ shipping address]
4. Create Midnight Delivery Module with midnight delivery Charge in Checkout.
5. Create Customer Desired Time [Date is already there] in checkout. If City and Time matched with other older order, then disable the available time by plus-minus 1 hr of ordered Time.
6. Fix some small issues with current OneStepCheckout [ basically some module are not displaying with current onestepcheckout. so just you have to fix those]
1. Assign / Delete / Edit City with each State [State - City Mapping]
2. Midnight Delivery Configuration
3. Functionality for Desired Time change from Admin > Sales > Order
Only Interested developer please BID.
