Cannot Install WP- Get error 403 message

I cannot install wordpress through my domain name http://www.esotericglamour.com as I keep getting error message 403 (you tried to access a document for which you don’t have privileges)

I have uploaded the folder “wordpress” via ftp using filezilla. I have changed all the file permissions for every file to 755. I have tried to upload a separate file (ladies.html) to check there is no problem with the domain name- that’s fine, I can see that file fine. I have also uploaded the same file to the wp-admin folder at http://www.esotericglamour.com/wordpress/wp-admin/ladies.html which also works fine but as soon as I try and open any of the wordpress files, I get the same error message.

I’m going mad…… Please help!
