First of all, you need to find the right market where you will be selling it,mark out your aim and events,however you will need to make a lot of research in order to find where to launch some new offers for customers. You need to attract them and inform them about your quality services first.
Well, in process for that, you need to do more optimisation for your site. Start with the basics first,that is Forums,blogs and ofcourse web directories.
Make your website more visible for others in search engines,some forums also have their offer section, you could post in there.Please make a note, if you spam a forum, you are never going to get potential and genuine customers which should be your prime aim.
All the best for the start and i believe with this you will get a great push. If you need any more information, please let us know and we will certainly help you out.
