BigCommerce Product Page customization

BigCommerce customisation expert required. Please do not bid if you do not have the required BigCommerce experience. I need a quick customisation of the product page. The site sells contact lenses and the customer must be able to select lenses for both right and left eye on the same page as well as quantity for each eye. The product page should have the following look like on these websites: h**p://[login to view URL] h**p://[login to view URL] h**p://[login to view URL] This is exactly the feature that I want. Being able to choose option for both eyes separately on the same page including separate quantity for each eye. It should be done preferably using options and options sets but if javascript or other code customisation is required then ok. All changes on the BigCommerce code must be clearly shown and commented. Please send your portfolio of BigCommerce work you have done on pm. Project will be paid after the solution is shown to work on a demo site you will create.
