Honestly I have no idea how to market this

[Dave A]

So a TV advertising campaign is out, then

There isn't much sense in trying to get consumers to an empty site. What you need to target at the moment is businesses to list. Once you've got a few onboard it'll get easier, but those first ones are probably going to take a lot of hard, focused, frustrating and massively inefficient work.

If I can get 10 businesses to register and upload their products in PE...

I'd suggest that would be a good start.

I still struggle to explain what this service is.

In my opinion (for what it's worth) this is where you should be heading:
For businesses it's online advertising for Rx per month with a 3 month free trial.
For the consumer, it's an online comparison shopping service.

Hi
I don't understand what you mean about your product and seem to doubt about it...

You have a idea,but now the idea don't have efficient structure...set yourself up a plan and see where you can improve....

Thanks Gino
