Get yourself and old windsurfer boom, old steel frame road bike, some bits and bobs and there you have it. A tidy bike trailer for kites, kiteboards and other bulky items.
Image doesn't appear to upload. Apologies
They say a picture is worth a 1000 words.
Your attempt to do it in just 31 pretty much proves this point.
A photo would be good though 
Here is my $70 kite buggy (converted kid carrier). I go to Rotto for 2 x 1 week holidays/year so needed a trailer that would pack small and be able to get my kite gear around the Island.
Holds 2 kites, 2 boards, harness, wetsuit and 6 cold beers.
