Replying to Binding screw broke!

hey guys, ok so i have rossi sas 140 ti's mounted on my green lifes. i was putting a sticker one them and i found that the heel piece had a screw popping out. i was able to lift the screw out, and thats when i saw it was broken. in other words, half the screw is in the ski. so, what should i do? i can either go to a shop, or should i try myself? im good with tools, and i was thinking of screwing a tiny hole in the screw in the ski, then extract it. im not down to remount them...

have any of you gone through similar experiences?
