Kickflip - Goofy Stance HELP!!!?

Hi, I've mastered ollies now I thought it was time to advance a step...Kickflips. Whenever I flick the board it doesn't always land flat, maybe upside down. That is just one of the problems. My other problem is whenever I try to land the board ALWAYS goes in between the middle of my feet, like my right foot and left foot are separate and the board is in the middle. I can't seem to find the right position to do a kickflip, and no matter what I do, no matter how hard I try i always turn so the board is ALWAYS in between my legs. My stance is goofy (I push with my left foot while my right foot is on the board.) Please help I want to land kickflips so bad!!!!!
