Also who pays to ride a skatepark? We have 1 small one round here which is always empty, due to 4-5 local parks which are free. If you think your going to persuade a hard nosed business man to invest then you need to massivly scale down your project, think about profits, break even analysis's, maybe make a USP of it being inside so your almost guarenteed to have riders paying to ride when its raining (which is a lot of the time) and parents paying to know that their kids are safe etc. And you really need to get the location right. Why are you trying to get 3 totally different riding disciplines in the same place as well? If you come to ride BMX you will ride the skateparks and BMX track, if you come to ride trials you will most likley only ride the trials rig, and DH riders will only ride the downhill... finding 15 acres cheap, in a place where there are a lot of people to come and ride??? your mad. Sounds 1000X less plausible than my business studies CW where I made half the shit up. (just to clear up my CW was 10+ A4 pages long, with break even analysis, ballance sheets, monthly forecasts to calculate the liquidity of the business, design and planning costings, analysis of opportunity cost....... etc. I re-drafted this about 10 times fully. You have put up 3 poorly spelt / arranged infomation which is very dissapointing for me. Seeing as my CW was only about setting up a tiny sandwhich shop and your planning to design and build a multi million pound project, on no technical basis)
