Workflow :: To Send Notifications To Multiple Supplier Email IDs?

I have a custom concurrent program which has a SQL query which returns multiple rows. Each row is a for each supplier e.g. 

Supplier1      sup1@gmail.com     123     5000Supplier2      sup2@gmail.com      456    4000Supplier3      sup3@gmail.com      789    3000 

This set is returned based upon some criteria mentioned in the where clause of the SQL.Ultimate aim is to send 1 notification to each of the email id's and those notification should have the corresponding attribute values. 3 notifications fired from a workflow triggered by the concurrent program (which actually returns this 3 rows in a SQL)Supplier 1 to receive  5000Supplier2 to receive  4000Supplier3 to receive  3000 My approach / or the only approach coming in mind is using a cursor for the SQL inside the concurrent program and using a for loop, initiating the workflow each time for a loop iteration i.e for each iteration of loop , workflow procedure will need to be initiated, so item type will be same but item key will of 3 different item key.  is it somehow possible to fire only one instance of workflow and not 3 different instances to send 3 notifications. Ad hoc role creation would not be option here because the number of rows may be large and not just 10-15.
