Create the simplest Woocommerce Theme for subscriptions

Hi. I need to get the simplest Woocommerce Theme for subscriptions for using in a marketplace which looks like this website [login to view URL] It needs to has: 3 categories only (one time, monthly and yearly) and 5 products max. per category to show to the shopper. It also need a form entry with 4 lines only: Name, Last Name, email and phone. And a Subscription (submit) button which will be used by my backend.
