Any ballpark on what that would/should cost, so I can start saving?

Thanks again,

For it to have a hope in hell of working there needs to be a good membrane connection of 
the roof up and over over the plate under the door sill and the plate itself needs to have a 
slope (I usually specify plastic lumber sill with the top planed to a bevel). The membrane 
over the sill also needs to extend up the door jamb forming a continuous waterproof seal.
