I guess it's hard to say how your prices stack up to other businesses in your area? I'm assuming you researched all of that and decided where you wanted to fit in though.
As for why they're not biting who knows? Is there any way to discern whether it was 300 people looking once, or 50 people looking 6 times? I guess on the bright side, even though you had no takers, you at least know that the outlet for your advertising is successfully reaching 300 people (or 6 very undecided ones
)
Are you counting hits on that particular webpage of your website? If so, I've looked at it about 3 times based on your website help thread! Or was there another advertising outlet?
