You could also speak to your local steel fabricators. They usually employ an in house engineer who can calculate a steel beam size. This will usually be cheaper than any of the big lintol manufacturers such as Catnic, IG, Keystone, etc,.

However, you may have to install a cavity tray above to prevent damp penetration.
