Oklahoma Vw Cruisers

I've had my VW Vanagon for a few years now and havent' had the chance to restore. The inside is in pretty good condition; it's the outside that will take quite a bit of work. I bought a new canvas for it, but the first thing that needs to be done is removing the rust which is the part I don't know how to do. I don't have alot of money to put into it, but I would like to get it looking better! I'm currently debating whether to keep it or not. If anyone has any suggestions on where I can take it to get the rust out and any additional help for a reasonable price please let me know. I plan on attending the VW Swapmeet! Thanks for your help! Check out pics below (the pics are a little older and don't show the new curtains or upholstry):

Very nice!!!

its almost like you could take it camping.. or even a road trip .. thats a really good idea..
