Woocommerce / wordpress functionality

[login to view URL] is a custom cabinet manufacturing company who are designing their new site. The website platform is wordpress using woocommerce. It now need some customisation from a developer to allow the below functionality: - Before the user can add any cabinets to their basket they must be prompted to choose from available colours of units. This will appear to the user as a pop out swatch of some kind. Once the colour is selected the user can then select and add cabinets to their basket. The colour won't effect the price, we just need it adding to the overall cabinet purchase. - The user would also have the OPTION of selecting the kind of door they would like for their cabinets and the colour of that door (from a swatch of available door styles & colours). The door choice option would be calculated per cabinet automatically base on sizes pre-configured on the site so the user wouldn't need to keep selecting after each cabinet select. This would mean once the door choice and colour is selected, the door sizes and the number of doors are calculated automatically and the door cost is added to the cost per cabinet. - There should be a button/link that enables the user to revise the colour of the board, the door and door colour at any time. - I need it easily updatable for me adding new door sizes & styles and cabinets to the website The above would be very similar functionality as [login to view URL] I'm currently adding content to the site with a lot more to do but so far I have completed cabinet pricing and sizes for categories 'base units' and 'drawer units'. I have added door sizes and pricing for the Vogue range of doors, the doors have been added as products and the sizes as product variations. These completed elements are ready to demo with the functionality I require. Can you please advise me how you would achieve the above so I can understand the method and confirm it is what I'm looking for. Similar woocomerce/wordpress project experience would be an advantage.
