Congratulations - you are on your way to a fabulous adventure.  Break legs!

I agree with the above - almost any Neil Simon will sell well - especially Plaza Suite, The Odd Couple, Barefoot in the Park, The Sunshine Boys or Lost in Yonkers.

Other comedies:  I Hate Hamlet, Blithe Spirit, Shakespeare Abridged, Art, and Moon Over Buffalo.

Also, a thriller like Deathtrap, The Mousetrap or Wait Until Dark - these have relatively small casts (no more than 8) and will delight your audiences.

Lucky Stiff is a musical farce - very funny - and can be done with a small cast if you double parts, which can make for very funny costume and make up accessories.

Another musical I Love You, You're Perfect, Now Change - 4 actors - and everyone seems to do well with ticket sales for this show.  Or try The Last Five Years - two actors singing about their relationship in opposite order.  A very good piece.

Dramas will not generally sell as well as comedies, but On Golden Pond may be one of the few exceptions to that rule.

Again, congrats on your new adventure!
