you don't need to go anywhere...
do you have color printing capability from your printer?
if you do, then you're set. otherwise, make a master copy and then head off to kinko's and the color xerox machine.
a line sheet does not need to be slick. it needs to be informative with a bit of creativity, show who you are, what your company is about.
my line sheet is 3 pages (8x10) printed on each side with text and photos, stapled at the top. simple and straightforward.
i print out a few at a time, when i need them. if you are at the beginning stages of business (or wholsaling) you needn't print a huge amount, you may change your prices or terms soon.
if you are interested, i could send you my line sheet as an example, to get you started.
shoot me an email if you want.
