I've raised £500 to My World Scout Jamboree experience.

Hello, I'm Mackenzie, I'm 15 years old, and I am raising funds for a once in a lifetime trip to America with the Scout Association.
The World Scout Jamboree takes place every 4 years and is a great opportunity to meet other Scouts from around the world. In 2019, between 50,000 and 60,000 Scouts are predicted to attend from over 150 countries. It's being held in America in the State of West Virginia and includes time on the campsite there (The Summit Bechtel Reserve), some time in either New York City or Washington State and then some time spent in a scout hut somewhere in either America or Canada.
Before all this became a reality I attended 1 of 2 selection days where myself and 32 other children worked in teams through a series of activities during the day. In total over the two selection days 65 children attended, and with only 36 places available it wasn't a given that you would be accepted.
My next task is to raise the amount of £4000 to enable me to attend. The £4000 is split into two sections: £500 for pre-Jamboree camps and the other £3500 for the Jamboree itself. This money should be raised in any way possible from fundraising; to grants; to Crowdfunding. Already, I have run a table-top sale in a local village and a disco to raise funds. At these events I raised about £400. To keep up with my progress follow me and Hereford and Worcester WSJ unit, on twitter, at:
