We have a new range of products that we can sell to our existing
customers . We have always found face-to-face representation the best
by a long way. However we have very limited budgets , find
'advertising' [and or unspecific promos like mail outs ] brings very
poor results , and only have two sales reps to tell our hundreds and
hundreds of customers about these great products they are either
buying off someone else or buying a competitive product . I need ideas
for good , cheap , effective cross promotion/marketing to speed the
awareness up.
