Configure Wordpress site that has been transferred to new host / domain

I have developed a site that is hosted and working fine on [login to view URL] and I need it transferred over to a new hosting service and the domain xxxxxx.com. The files are already copied over, the database has been changed and updated from .ca to .com. I am just getting a blank page on this new domain so I need someone who can get the site functioning. It will be something to do with htaccess file or [login to view URL] or wp-config file etc. the database or whatever. Your mission is to get this site up and running on the .com domain just like the .ca domain. If you have the skills to accomplish this and can do it soon, I would like to hear from you. I can assist via email (or even phone if you are located in US or Canada) with all the details.
