Can you give us a bit more info? Do you want to lay concrete flags on top of an existing crazy-paved surface?
Have you read the page on Damp Proof Courses? Will you have sufficient room to accommodate the concrete flags plus the requisite bedding?

You've got the basic idea right, but I recommend a semi-dry mix, rather than a wet mortar. It gives you more working time, it's cleaner to work with, and it's less likely to cause the flags to 'float' during the laying process. 8:1 or 10:1 grit sand to cement should be strong enough.
Don't forget to allow for drainage, and to point the joints with a Class II mortar, as described on the Pointing page.
