customisation related to products options displayed in all listings,quantity selector & add to cart button for auto suggest products in ajax search,+

Hi Currently I am Using opencart 2.0.1.1 and Journal Theme 2.5.4 and I need the following customisation for my website. 1) I need to show the options for the products along with the options to select quantity at the home page,category page,product page (it is altready there) and all the modules and listings where the products are listed and [login to view URL] selection of the option the price and image should [login to view URL] the add to cart after selecting any of the option should directly add the product to the cart without any intermediary changes(This feature is already there and shouldn't be changed while customisation).The product option inventory also needs to be managed individually.I am currently using import export tool by jnheuoff and the customisation done should be linked with this tool so that I can bulk update the options for the [login to view URL] special pricing or offers and the journal features like countdown timer should be available on each option of the product and the option to apply them individually for each option separately if needed. 2. In Ajax search I need to add qty selector and add to cart [login to view URL] when products show up in auto suggest,the products which have options and availability in stock should be broken up and displayed serialy in search suggestions so that customers can quickly add any variant of the product from the search auto suggestion itself. 3. In user account - order history page I need to add "reorder total" button so user can reorder a total previous cart in a single [login to view URL] needs to be two button,one which will add all the product in the order history page to the cart for further modification or addition deletion of some products and another button to checkout with all the products in the order history to the checkout [login to view URL] needs to be available in all the order history when the user logs in and checks order history. The customisation needs to be done in strict opencart structures and mvc structures and pattern so that it is compatible with future opencart versions and Journal Theme updates Any expert opencart developer with relevant skills is welcome for the job.
