Build a Multistep Checkout Process for WooCommerce

We want to build a store similar to the one here: [login to view URL] Our site is here: [login to view URL] (store page) We want a four step process that should be similar to the FreshFilterPlus site, All options should be displayed all on one page with tabs at the top which they can use to navigate back and forth. The products are the same as the site above but we are just trying to sell locally to keep in touch with our clients. Product 1: Merv 8 Filter with 76 different sizes Product 2: Merv 11 Filter with 60 different sizes Product 3: Merv 13 Filter with 41 different sizes Preferred order is: Step 1: Select Size Step 2: Select Filter Type Step 3: Select Quantity and Schedule (every month, 2 months, 3 months, etc.) Step 4: Checkout I understand that each product has different sizes. If need be we can do this order: Step 1: Select Quantity Step 2: Select Filter Type Step 3: Select Size and Schedule (every month, 2 months, 3 months, etc.) Step 4: Checkout We have WooCommerce installed along with WooCommerce Subscriptions and WooCommerce One Page Checkout. We just need a way to integrate these into the same flow as the model site mentioned before: [login to view URL]
