Woocommerce template changes

I need someone to customize my WooCommerce site to make some changes to the template. I need this done immediately. Project will be awarded only if you can start on this now. I can show you the site if you would like to see the scope of the work before you are awarded the project. 1. The product "Price" should only show on any product list/page when a user is logged in. a. This is currently setup using a plugin which I'd like to get rid of. b. The price and code should never show to a visitor. 2. Update the single product page to show custom product attributes on right side of the page instead of using tabs. This should only happen when they are entered for a product. a. The custom product attribute:Colour should show the swatches on single product page. - I have a plugin that could do this, use the plugin or update the template. b. Customize custom product attribute:Code to show only when a user is logged in. 3. Show "purchase note" on the single page view. 4. The SKU and Category are on the same line, put them on two lines or add spaces between them. 5. Make changes in custom theme so they are not overwritten if wordpress, woocommerce or my current theme are update. - Show me where these changes are made and stored so I can backup and replace if they get overwritten. thanks.
