I would like to hire a Programmer

Hi, I need help with e-commerce type page with 150 items where a logged in user can: search for items narrow down items by conditional dropdown menu/ form save items as favorites. The price of each item will be conditional upon an input field (for a number) that the client enters and a formula from an excel worksheet. I also want a resale price for each item to be listed, also conditional on input field. Ideally it can function with wordpress and woocommerce or another similar platform. Basically the price of the products needs to reflect a formula that relies on the customer input  So the customer can login,  then input the number to see the prices reflected, either at the top of the page, or on the side bar.  The formula will looking something like this:  (input x 0.25) + (input x PvalueA) - (input / 1.4) x (Input x PvalueB) = Product price $ We will be putting the PvalueA and PvalueB for each of products on the backend.  So customer puts in 2.5 for input, the formula is calculated and all of the prices change to reflect the calculation.  The products will each have the same formula, with only the PvalueA and PvalueB changing. Product 1 (input x 0.25) + (input x P1valueA) - (input / 1.4) x (Input x P1valueB) = Product price $ Product 2 (input x 0.25) + (input x P2valueB) - (input / 1.4) x (Input x P2valueB) =  Product price $
