Wouldn't it be easier to work another job and bill the correct amount

but I did a 1000times it would also be earning me  £100,000..... so that extra £8000 is'nt going to be a problem

Then your tax wouldn't be £8000, it would be around £40,000 (higher tax bracket) but would still leave you with a £60,000 profit minus materials, petrol, wages and time.

Mind you you would then have to pay 40% on all your other work and be VAT registered (if you're not already)
