Hi Dene,
I would suggest operating as a sole trader to start with and see how business takes off. LTD companies are good but costly with accounts, time consuming and unless you are tendering for large commercial contracts not a necessity to start with. If you are raising lots of capitol from banks etc... to start your business and have high overheadss to begin with then maybe the LTD company is a potential, although nowadays its changed, if the company goes belly up they look at you and your personal situation before writing debts off. Not meaning to sound negative but just realistic.
Good luck hope you enjoy the carpet cleaning business. Where are you based out of interest??
regartds,
