Repaints are pretty expensive. For a mini-van like your T&C you can expect to pay anywhere from 1000$ to 5000$ depending on the quality of the job you want and the amount of repair they need to do before painting. The prep work is the most expensive part of repainting, so if there is any rust, dents or any other kind of repair to do before they can paint the cost will quickly increase.
If you are someone who likes projects, you could do the job yourself. The least expensive would be to do a rattle can repaint. This will cost you around 200$ and take about 2 days of your time. The quality of the paint job will be poor but it sure is a big improvement over a peeling clearcoat.
You can plasti-dip as others have suggested, this is more expensive. You would have to do research on cost but I would expect something around 500$. Personally I don't like the look of plasti-dip but that is a matter of taste.
Finally if you have good compressor, you could get yourself a paint gun at harbour freight for about 30$. This would make a much better paint job than rattle cans. Cost of paint would be around 200-400$ depending on color and quality. For this you need a compressor with a good air reserve (40 gallons or more) and decent air output (at least 10 cfm). If your compressor is small you would have to take your time and do one panel at a time instead of shooting the whole car in one go... but it can be done.
Generally it's not worth having an old vehicle repainted professionally because the cost of the repaint will exceed the value of the vehicle and it adds little to no resale value. In your case, the vehicle is probably worth about 2000$ so having it repainted for say 3000$ would make no sense.
If you want to learn how to paint yourself, there are a gazillion videos on Youtube about DIY paintjobs from Rustoleum roll on paint to almost professional quality paintjob.
Hope this helps, and have fun what ever you decide to do
