The link below downloads a .psd file with two included BG's, all the characters/classes (in proper places and sizes) (layer style easily altered) and monsters (none of the above but they are there if you want to do something with them).
Text is also easily altered.
Feel free to use anything you like.
+ this signet...
PS. YOU WILL NEED PHOTOSHOP, POSSIBLY CS5 EXCLUSIVE, BUT NOT LIKELY!
EDIT: I know the last signet is poor work, I was just experimenting with other sizes than 700 x 200 and threw something together quick.
