Q. range 200-300 dollars.
A. back in the day of analog, it was impossible to do green screen effects from video tape. the foreground object had to be a live camera and nothing else. the backgound is unimportant, so that could be analog tape. Then came miniDV and that changed everything. miniDV offered chroma resolution that was 6 times sharper than VHS. so for the first time the forground subject could be recorded on tape and a computer video editor used to make the overlay. Now that we have modern file base cameras that use SD cards or DVD discs. These are super compressed, with 200:1 being typical. So now the foreground subect blurs or pixelates into macro blocks any time there is motion, spoiling the green screen overlay even from so-called HD cameras. So Pallidin is absolute correct to suggest that you need miniDV camcorder.
as to the greenscreen, that can be anything. personally i prefer cyan blue as that gives a sharper chroma contrast to skin tone. TV studios usually just paint it on a wall (wow you thought this was high tech?). me, i used king size flat bedsheets, not having a suitable wall to work with. The secret is in the lighting. the screen needs its own light and it must be even top to bottom and side to side. the subject has to be lit from the top angle to prevent shadows on the screen. unless seated, it is hard to do in a normal room that has only 8 foot ceiling clearance. if you have a garage with open ceiling, use that for the studio. Also you need to put a light behind the subject, some times call a hair light. This sharpens the hair line at the top/sides of the head, after all you don't want your leading lady's platinum blonde to turn green due to a poor key.

A Camcorder For Green Screen?
Q. I am looking to buy a camcorder for under $250.00 that is atleast descent. It needs to have a microphone jack that i can plug in a lavalier mic into. Im going to use it for green screen so there will be lots of light. Thankyou for your help.
A. I wouldn't recommend anything under $400 for chroma key (green screening). You really should be using either a 3CCD camera (a separate chip for each color, Red/Green/Blue), or a good CMOS chip (a different chip, it's single, but can be great).
The Canon HV20 has a single CMOS chip that is excellent with chroma key. But basically, anything under $250 will be a challenge to key out in editing because of the inefficient color capture. You could check out www.camcorderinfo.com for some ideas, but the style of camera you are looking for doesn't match your price range.
Sorry.
