MYOB Premier Integration with VOLUSION ecommerce CRM provider

FULL Integration if this is possible. However if not a format which allows DATA Import/Export between the MYOB Premier and Volusion store online would be sufficient. I imagine it would be a matter of matching up the relevant fields on each side. Advise cost and solution/suggestions. DATA which needs to be imported to volusion includes, customer cards, Inventry, etc. We want to export Sales from volution to MYOB - so Inventry is updated and Invoices are entered in the system. Vice versa from MYOB to Volution. Please provide quote.
