What is the price per square foot for painting new drywall?

The short answer is the lame one ... it depends. I assume the person who submitted the question is referring to a ceiling texture in a residence. Also assumed is that the drywall has been finished to level 3 specifications; meaning the drywall has been taped, bed-coated, then skim-coated with joint compound. Additional factors may include whether the ceiling can be reached from the floor or the job requires the use of scaffolding (which would double the price). A quality contractor, such as one signatory to the International Union of Painters and Allied Trades, will produce a texture that is evenly applied and produces the subtle effect of "softening" the room. You will pay slightly more for the higher quality. For texture only (assuming the above caviats) expect to pay 10 to 15 cents per square foot. You may be able to find a qualified drywall finisher for a lesser price. Check the paint store. Keep in mind that just because someone gets paid to do a job does not mean he or she is a professional. If you want the highest quality contact your local IUPAT union office and ask for a list of signatory contractors.
