Self Employed credit card debt/balance transfers

ruddster

Help!

I have amassed a total credit card debt across three seperate cards of £21000. I want to try and move this all to one card with a 0% balance transfer. Whilst my credit rating is the best you can get my income has dropped considerably and if I were to declare it truthfully I dont think i would be accepted. Does anyone how indepth the income checks would be on me as a self employed person? Would i have to supply bank statements etc?
Anyone suggest how i may be able to do it without actually having to prove my income?

Thanks
