Post 25-50 ads for the next 2 days and ill hire you for job posting everyday.
you must make sure that posts stay up for atleast two hours. Posts must have all info filled in (title, price and area) and it must look professional. dont overuse characters to make my posts look crappy and annoying.
Ill supply you with 2 ads for 1 category and we will see how you do. post on phoenix > computers > for sale by owner/dealer > west, central or north (ONLY!)
