However, I am not experienced in business that I can advise you. But, as of my opinion you should look for some opportunities online if you are looking for making sales. As you will find some of the companies which can boost your company via marketing services. It will cost you money but for the trial also many webs give. You can also look for sites where you can sell products like on playerup, Digistore24, etc.
If you are looking for marketing via email, you can use Herculist Plus. Although, they have a free version which sends 1000 emails to their members. Other email marketing service is also available. I can't remember the names of them right now.
