how do I sell a hobby caravan for 2 gran wot needs help?

Through a great system that's been in place for thousands of years in two parts.
Part 1 bartering meaning to exchange/swap for something else material Part 2. Advertising.
So its up to you to choose which ever generates the most. However do the two gran's that needs help know your selling their caravan? or will the money you get be used for their help?.
