CRM / SQL integration to google calendar and quickbooks

We are a small business. When we create a sales order or work order we would like it to a) generate a calendar event in Google Calendar for scheduling with certain info from the form showing up in the calendar event, and b) to generate an invoice in Quick Books. We currently generate our work orders in Excel and Access but want to move to a SQL database form type system. An open source system that might be a good platform is MyIT CRM at the link below. You may have alternative favorites as well. We use the Contractor version of QB. [login to view URL]?action=logout UN=admin PW=password
