Be careful not to apply for too many credit cards at once as this will start to affect future applications if you apply for more than 2 every 6 months.
There are plenty of 0% deals out there from various issuers. Have you thought about a life of balance deal - as this would give you a low rate until you paid the balance off in full so you wouldn't have to worry about switching every year or so.
It's worth using a comparison site, like
Credit Card Comparison Online for example, so you can see all the different deals in one place.
Good luck!
