If you want a basic, inexpensive L-Bracket, for switching from landscape orientation to portrait orientation on your tripod, I can suggest this $14 bracket from Am-a-zon. It ain't fancy, but it'll get the the job done. Assumes your tripod uses an Arca Swiss release plate, however.
If you need a flash-bracket I can't be of any real help.

Well is not for the tripod though, it is to mount the flash on the L bracket, and the bracket mounted on the camera. So, you can flip the camera and bracket for portrait and lanscape.. Thoughts...!
Well yeah i know that. There are tons of photos about Flash Brackets but they do not specify you can move it this way for portrait and this way for landscape in flash photography
