Moving from localhost to blue host

I’m trying to move my website from the my local development host to Blue Host. I’ve populated my database be exporting my local database from the MAMP phpMyAdmin and replaced the localhost stuff with my url. I’ve populated my database on Blue Host and uploaded all of my files via an FTP client (Cyberduck). I’ve also edited my wp-config file to include my database information. When I go to http://www.sunday-studios.com/wp-admin/index.php I get a 404 not found page from Blue Host.

I feel like I’m making a simple mistake. Anyone out there know how I can fix this problem?
