flushmount tonneau cover, where can I get one?

Im looking for a hard flush mount tonneau cover for my 93 ext cab, but I cant find one. does anybody got a link with a price?

Do what i'm fixen to do.
I going to a local alum. boat shop and going to get them to take a sheet of alum. and bent it on all 4 sides and Install some supports on the under side.
Then i'm going to make some brackets and put linkage and shocks from a reg. hood on it and call it done.
The guys at the shop said that the alum with the bent sides and supports would run around 100.00
Thats not bad at all and it will be a flush mount as well.
