Extend and create feature wordpress booking plugin

We need to create new features and extend the existing ones for the wordpress plugin "Booking System PRO": [login to view URL] Currently the software allows to create, modify and attach different calendar at different woocommerce product, showing the booking in the product detail page, but unfortunately it lacks of some important features for the standards in the booking business software. We are working on a website where each hotel can have a personal space for informative material of the structure and a booking part with rooms and special offers. The website is developed with wordpress and woocommerce. With the current software the potential client must watch every room or special product one at time and this is not acceptable. We need to implement a search function that shows the results according to the date availability, number of adults, childrens and rooms. For example a system similar to this: [login to view URL] (except for the search by hotel) The main feature that must be developed are: Search function: - on the left (1/4 of the width of the page) a search widget according to date availability, number of adults, childrens and rooms, a calendar for the choice of days and a button for searching the selected room/special offer with that criterias. - on the right (3/4 of the width of the page) a space that when the search button is pressed, it will shows the result of woocommerce products compatible with the user choices, in a list preferably with the plugin "[login to view URL]" or a similar style, and the possibility to go to the detail page of the product and add to cart. - implement it with a shortcode to insert in wordpress page, with the choice of the category of products to search from (every hotel will have a unique category, for searching only their rooms/ special offers). Booking feature: - implement a system for insert different price for adults and childrens. - add category and subcategory to every calendar created. - assign every calendar to one or more woocommerce product. Software testing for solve bugs. We know that the work is not simple, but we search for the best developer that can get the work done in max 7 days and start very quickly, because the situation of our business is critical and we really need this booking software. We are happy to give more detailed and technical information for the project before to start, and we are open to new ways to solve problems and develop what we want. Excuse me for the bad english, but this is not my first language.
