Kayak Hire/Tours

I dont think this is good idea, becasue the British always have rain .if rain you dont be used hire kayak,you will be lost your money.In the high street I think they have hire boat for everybody,about 9 pounds for each hours,this is good profit,those boats dont need to many costs and you can use long time .but if you want to do this business,you need to make the license,I dont know how much money you need to pay ,but I am sure that is not cheap,assumption you are get the license ,how can you use the river ,it is free or you also need to pay money for somebody.this I all dont very understand.also we are not professional ,the kayak is not easy for the new person,I think if you are first take the kayak,maybe you will get some problems.sometime will be lsot life
So I think this hire kayak has big business risk,maybe this is good profit .
