Looking to build my own cart (newbie)

Hey guys, I'm from Athens, Oh and looking to cater to the college kids and business professionals in my area with a hot dog cart. I am wondering if there are anyways to build my own cart and cheaper ways at that instead of paying $3,000 for one. Any help would be appreciated. I look forward to interacting with you all on here! 
 
Have a great day!

sure. there are a few places that sell plans and parts. and books on how to setup and run your cart too. bens carts is one. http://benscarts.com/ he sells plans and parts kits. and most things you would be for your cart. plus he has good service and fair prices. i.e. most people charge up to 80 for a dog sled, a prep area to build and set dogs for customers, I have seen these for around 20 dollars at times.
p.s. I do not work for bens carts or get anything for my opinions.
