Ok, you've been given VERY sound advice up to this point but magicians being magicians they will typically ignore logic and run out and shoot themselves in the foot by taking the gig and trying to do material that's impractical, poorly rehearsed, and rarely anything that will prove memorable.
What kind of cash to you have on hand? Money can sometimes give you the remedy. . . that is, if you know how to count to 100 and read something as advanced as the Brother's Grimm. . . I'm not kidding. Sock a bit of cash into classic routines like the Canary, Egg, Lemon and Orange or the Gumball Machine from Collector's Workshop and you will have something memorable so long as you can give clear, fun patter. They are relatively easy to work and execute BUT YOU MUST SUPPLY THE CHARM!
These two examples will probably make you stand out from most other magical talents in the region in that the typical mage in cow town U.S.A. will be buying in quantity vs. quality of prop. . . they'll drop a hundred or two on a simpler "Kiddie Show" prop in the majority of cases vs. a few K on a big feature piece. That said, you might just look at putting a twist on an old classic and pick up a decent prop used, via Magic Auction or a similar sight. Pirates are a big theme these days, borrow it and iron out a pirate act that involves treasure (Miser's Dream +), Swords (don't do a Card Sword, that's too typical. . . there are several "easy to make" pieces that you can make for cheap, so long as you have a few decent swords laying around). Maybe even chop off a peg leg with a Lake's styled chopper?
But then, that would take time and your dependence on a team to make it come together. . . do you have such assets as well as some cash to throw at the concept?
You see, I can't help you until I know your skill level, area of interest when it comes to stage, etc. I can feed you ideas and point you in a myriad of directions but as you can see, being able to fulfill this sort of obligation requires two key elements; Time & Money. . . at least $1,000.00 to as much as $10,000.00 depending on what you and a more experienced performer can come up with. But then we come down to time; even if it's only you, it takes time to practice and rehearse an act that you've written a script to. It takes time to study your "dailies" (video shoots of your rehearsals) and see what you need to fix. . . it takes time to get costumes ready, to customize your props, etc.
BUT. . . If you have 3-6 months to plan things out you can make it happen.
