Since it's already April, try to find some plant in your local nurseries, should not be hard at all.
In general many cayenne, thai (orange, red, dragon, ...) and indian peppers (like Pusa Jwala) will do and are usually available everywhere.
Also Goat's Weed if you can find it and like something a little out of the ordinary.
The local indian/asian community should be a great source for seeds for the next year.
