Integrate existing WooCommerce/Wordpress E-Commerce site with Xero and Hubspot

We have an existing WooCommerce/Wordpress E-Commerce site, and need it to be integrated with our Xero account (for auto populating customer fields and sending out VAT invoices) and with our Hubspot crm (for ongoing marketing and management purposes). Additionally we will need the site optimised to enhance the user experience.

There maybe a requirement to integrate with other third party software (e.g. ad design), and social media sites - but this maybe a separate future project. You can see our current site here www.smartermedia.shop
