Where are you going to terminate both ISP? Is it a seperate router or the same?
For simplicity, just ask your ISP to advertise default routes to your router. Of course you need to create an eBGP peer to your ISP. Then create an iBGP from your internet router to one of your internal router. Advertise the default route to your iBGP peer router by using default-information-originate under BGP configuration.
Redistribute BGP into IGP into your internal router.
