Business and WooCommerce update required

I'm looking for someone to maintain and update my business website and WooCommerce. The website is www.boards4agents.com. We are looking for someone to make our online shop attractive, to get more customers. We need a complete refresh of the website - it's out of date and needs updating. The pricing on our WooCommerce also needs updating. How many hours do you think it would take? I think at least three, and then about 30 minutes per month going forward.
