Offering zero percent interest...

I want to offer 0% interest to my consumer customers.

Can anyone recommend a company that will give the financing (obviously I pay some interest) to me - a sole trader who's started up in the last couple of years and doesn't have a large turnover yet. I've had one person recommend ezipay, but they have a £100 minimum monthly interest paymant.

If I self-finance it I have to get authorised as a credit supplier, and pay for that authorisation.

Thanks
