Customize Woocommerce WordPress site

Need to add a few customizations to WordPress Woocommerce site (site already completed).

1. Add 3-4 custom fields to PRODUCTS and/or to Customer/User data and display those fields on a customized Order Summary (relaid out slightly); have the customized Order Summary be printable or save as PDF (attach PDF to customer email).

2. ALSO need to add a Locations/mapping plugin (internal data list of admin-editable testing locations, each with ID#, address, phone, email) and allow customers option to PICK a location at end of their order and SAVE the location to their order (so user places order for $100 product and then picks location #123 from map & display list of locations. Once user selects it, site saves location #123 into that order in DB).

3. LASTLY, need to allow the site admin to UPLOAD additional PDFs in future that will be attached to a customer/order– and they will be shown on customer dashboard/my account area, allowing customers to login to view/print/download the PDFs.
