lol if you dont want to listen to people in the trade then its a good idea to leave, dont listen to us, id love to hear from you in year when you come back and appologise that you made a total cock up, that your now minus £10,000 on the year due to buying the system, van,paying n.i ,public liability, van insurance, water bill, etc etc etc etc etc etc and that you cant now go abroad due to not having any money, I for one would not have any sympothy for you as you didnt listen but only to some sales pitch by a installer of the system, why not ask people like steve-cm, j.v.price, bluez, dave morris, if they think what you are saying will happen, go canvassing every night, then have to do the work, lose a load due to only wanting a one off clean, trust me if you break even in your 1st year then you have done really well.
