WooCommerce master for large site

We are in the process of developing a new site that will have lots of variations.

This site will use a plugging to scroll to the next variation.

We have lots of variations per product and that means lots of pricing updates.

We are looking someone either to make this process more easier or develop it so it works the way we need it ---------- 's for a UK client and if the job is done to a high standard it may mean repeat long term work.
