Site Transfer to new host - Includes PHP SQL Reconfiguration

I've already pointed domain name and transferred site files to new server. I'm having trouble configuring site to work with new server. I already created 4 new databases name and user within MySql Cpanel. Each time I attempt to import .sql file within MyPhpAdmin I get an error message: "#1044 - Access denied for user..." Note: New server has MySQL Version: 5.0.81-community This project includes: - Granting privilege to user to import/add database - Importing 4 SQL files - Configuring any/all site files (php) to match their database credentials & new server root - Ensuring no error messages appear on live site and fully functional Need this done same business day I will provide FTP and CPanel login details as well as send SQL files to import/query Thanks
