contact service

Have a list of suppliers and need to have customers contact them. They will have to sign up for account. Example would be, have a list of auto parts suppliers and customer would log in and make a selection of the make, model, year, engine type, and options. They could then select what they would like to have, say a used carburator. This would then be emailed to any suppliers signed up for the service. They would be charged for each email sent out asking for pricing. User will be charged for a small processing charge.
