Is it appropriate for me to get an IVA? I run my own one-manned company and so am a Director

I have joint mortgage with my seperated wife but do not live in the house except when I stay there to visit my kids.
I pay the mortgage and most of the bills in lieu of maintenance for the kids.
There is about £100k of equity in the property which I would prefer not to have to release as half of this is the seperated wife's anyway.

I have a total of £35500 on credit cards (all at minimum monthly payments for several years now) total monthly payments are c.£1000 per month.

I also have c.£7500 left on a loan (4 years left to go @ £109 pm) and I owe HMRC £6200 on account for 2009-2010 Tax Year.

Mortgage on the joint mortgage is c.£800 per month.

Utility Bills and my accommodation costs are c.£750 per month.

Other monthly expenses total c.£550 per month (car, food etc).

Total monthly income after deductions is around £3000.

i.e. 3000-(1000+800+750+550) = -100 per month but I also need to pay half of my tax bill now (£3100)

Also, can I remain a Director of a Ltd Company with an IVA?
