I heard that laptop manufacturers (HP, Acer etc) are going to offer a free upgrade to Windows 7 if you buy a laptop now, but that they will charge for postage and packing. Does anyone know how much each manufacturer will charge for them?

How much should I charge to install windows xp s3, ms office, arobat read, avg anti virus and then diagnose the hardware for 7 laptops? (Note: They provide me all the software needed) So what is the ideal price for labor?
