Building a balloon car is difficult. It is even harder to make a self propelled balloon car because even though it sounds simple it actually employs a lot of physics theories and a person would need sound knowledge about these theories. Hence it is not an easy job by any standards. There are sites and books which basically explain the theories used in a balloon car.
You can check out whether you understand them and are able to use them effectively. But it is not possible to make a balloon car for free. It would take a lot of planning, efforts, time and money. Hence it is advisable to think several times before venturing into such a project because leaving it mid way would cause a lot of losses.
