Custom Drupal Module(s)

General information for the website: Customize Shopping Cart For Drupal Site Using Drupal Commerce Kind of development: Customization of existing website Num. of web pages/modules: One or Two Description of every page/module: We need to customize the ad to cart form for a Drupal site that is offering Tours for sale. The site is almost complete but key elements need to be implemented. Each tour on the site has product variations that are all displayed on the tour pages (aka product displays) [login to view URL] need to collect a booking date when a tour is added to a cart. The tour date should be global for all variations that are being added to the cart. For example if there is a driver price and a passenger price both are product variations of the same product and they are booked by the customer at the same time and the driver and passenger will come together, so the date should be global. 2. The available dates should be controlled in the back-end and in the front-end only available date should selectable on the add to cart form. thing we have been looking at so far to do this: - the availability calendar module (not responsive out of the box) - [login to view URL] module ([login to view URL] is a good candidate for displaying dates in the front-end but it would have to be customized to only allow users to choose form available dates) 3. We need to control the minimum time before a tour can be booked. It should be at least 48hrs. Currently this is controlled by rules module globally but we would like to be able to set this per tour and disable dates in the calendar of available dates accordingly Description of requirements/features: Mobile first : Responsive Extra notes:
