Access 2010 Invoice/Billing System

I'm looking for someone who has major expertise in the access 2010 area. The application is for a Invoice/Billing System that can create invoices and use our existing WORD template to mail merge the currents month of invoice. The tables are finished, data has been entered, most web forms have been created. I'm looking to add web forms to give it a more user friendly appearance aswell as a more featured enabled filtering system. The system will need about a dozen or so queries to enable this. The system also needs to be able to mail merge using a word template (this is a huge feature if you can enable this).
