Optimization existing WooCommerce Store

Hello, We are looking for a development team who can fix certain things within our existing WooCommerce webshop. 1. Update Wordpress (with before making a backup of course) 2. Email confirmation, after registration + after order to send email. - Currently not possible to register (as user) - Currently does not send an email after registration - Visitors that register, should be added in MailChimp (connected already to store) - Currently does not send an email after order - Should be sending from domain of store 3. Order page, order page isn't presenting correct information. - Change link "Proceed to Checkout" to a button. - Setup API with PayPal for our third-party payment provider 4. Product Page, small change - We have added, when visitor is not logged-in they cannot see the prices, however, at the bottom of product page there is a 'Add to Cart' button, which anyway shows the price. When visitor is not registered, visitor should be forwarded to My Account registration page. 5. Small design changes - Change "Login to see prices" link to a button. - Change confirmation 'Registration' + 'Order' email to other design. As you see, small changes. For the right developer this is only one day work. Budget $100 We have more sites, so good work is rewarded to more jobs in the future.
