UK Local Authorities Contact List Wanted

We are a startup company and looking for the contact list of decision makers (Heads of Departments, Directors, Assistant Directors, Senior Managers) within UK Local Councils.

The list must be recent, in Excel or CSV format and must include TITLE, FIRST NAME, LAST NAME, JOB TITLE, EMAIL ADDRESS, COUNCIL'S NAME and COUNCIL's MAIN ADDRESS (as in address line 1, address line 2, ...., each in separate column) of each contact. Any additional information such as phone numbers would be helpful but not necessary.

The list must be licensed for multiple use, with no restrictions or requirement for additional payment. Also, we expect that no more than 15% of the emails sent to bounce back as a result of a contact having already left or made redundant.

We have a very limited budget for this, therefore please bid accordingly.
