I've just created a new app for Shopify. What I really want to find out is if there is a cheap internet marketing company that can do the marketing for me. I think it basically needs forum posting etc. I'm not trying to promote my app here, I just need some marketing advice on how to get some users!<p>My app has some competitors but also has some real differences that will add value to eCommerce type businesses and is the only app that provides those features.<p>Any marketing advice would be fantastic, but I really would prefer to pay someone to do it for me.
