Colin is right on - as usual...
Regarding flash brckets, there are many-many types available. I prefer the "camera-flip" type to the "flash-flip" type. With the "camera-flip", the bounced flash is always facing the correct direction. With the "flash-flip", you ned to readjust the flash when switching from horizontal to vertical camera positions. The images show the difference.
Note: I did not show the setup with the required off camera flash cord in order to simplify the image.
I use a Chinese knock-off
I use a Chinese knock-off of the Stroboframe brackets. I first purchased the flash flip model and then after getting tired of readjusting the flash head when switching from horizontal to vertical positions, I bought a camera flip model.
Another unique flash bracket is the Siegelite which can be used in several ways both as a macro bracket and as an off camera bracket for non-macro photography. It can also be used with a small umbrella (brolly) by attaching the unbrelly to the bracket and pointing the flash to shoot back into the umbrella.
The Siegelite bracket is only available used on ebay but, usually sells for under $20 (USD) when found. I use mine for macro work and I paid $5 (USD) several years ago at a garage sale.

By the way, you will see a quantum improvement overdirect flash by simply bouncing your flash when attached to the hotshoe. That is why a flash that both tilts and rotates is handy. I use a diffuser on my flash made by Jow Demb. It is relatively inexpensive.
