buy organic seeds.

grow organic fruit and/or vegetables.

sell organic produce to area fruit stands.

Offer people the chance to "open their own fruit stand".

Write a "manual" on how to do it and sell the manual for $100.

Sell the produce you grow to the buyers of the manual.

Do this for the rest of the summer, and you just might make your $10,000.

$10,000 / $100 per manual = 100 manuals sold.

It can be done, you just have to be willing to a) think outside the box and b) put in a little work on the front end.
