You didn't really say what your budget is but I'm guessing that since you're looking to sell a lens to buy the camera, your budget is pretty low. You are not going to find a professional top handle cam with flash memory capability for under $1200.
For under $400 I recommend looking for a Panasonic HDC-TM90. It is last years model so can be found new still for fairly cheap. It shoots up to 1080p60 in AVCHD, has manual control, 16GB built-in memory and an SD card slot. It also has a jack for a stereo 3.5mm mic input, HDMI out, multi-AV and USB jacks. The 10x f/2 lens is 28mm at the wide end. I have had this camera for about a year and a half and it has been very good for my uses. I would say its biggest downside is low light performance is not spectacular but, in this price range none really are.
Mount it on a top handle rig like mentioned earlier with a 0.7x adapter lens and you would have a fantastic skate rig for very little investment. Add a Rode Videomic pro later when funds allow...Done!
