Wordpress Multilevel categories and search-enabled

I need a wordpress with WooCommerce-enabled (or any suggested) . I will be offering car auto parts with multilevel ability of filteration; A good example would be as following: (dropdown list) Select Year: ex. 2015 Select Make: BMW Select Model: X5 Select Sub-model: X5 Premium Select Engine: 5.0LTR Select Specs: US Specs Result: a grid/list layout listing for all found products with specs of each. For those interested please make sure your ability to achieve the following: 1- products to be added easily via wordpress products. 2- easy categorization with no hustle 3- decent db structure and smooth loading 4- Wordpress enabled (you can suggest anything else but you need to proof your point) 5- A good example of what it might look like is .... [login to view URL] 6- interested candidates need to build a pilot page to demonstrate the above before any cash transfer. 7- Payment terms AND amount to be agreed upon pilot page results. (Project Size can be changed) 8- PS: WP free/pain plugins can be used as part of the overall delivery method. Please I don't waste your/my time in negotiating cost, deliverables ..etc. I would respond to the minimum to confirm receiving your offer only. If you want to pay my attention please provide me with the pilot page. Thank You!
