Chord Charts For Guitar

I need help with a few things. I have Central District auditons coming up soon, and though I may not get in, I still don’t want to look like a total idiot when I go! The requirements for guitar are about 10 times harder than any of the other instruments. There are much more requirements than I’ve listed, but these are the ones I need help with.

Comp all V7 chords*
Comp all diminished chords*
Play ii7-V7-1 Major Seventh Chord Progressions in any key.

*All chords means Ab, A, Bb, B, C, C#, D, Eb, E, F, F#, and G

Please show chord charts for diminished and V7 chords and please explain and show what the heck ii7-V7-1 Major Seventh Chord Progressions are! Thank you so much I will be eternally grateful!!!! Choosing best answer!
Thanks, man, that helped so much, but does anybody else have an explanation on what those ii-V7-1 Major 7th Chord Progressions are? Or what V7 chords are and the chord charts for them? Thnaks.

I wish you the best of luck with the audition. Try this site.
You set up any chord you want and it will show you. Again, good luck. http://www.all-guitar-chords.com/
