It is not going to be easy to sell your product since it is relatively new and there are popular options to choose from that are already available in the market with customer reviews.
I advise providing vouch copies to certain high ranking members of this forum so that they can review your product which could be the kickstart that you need.
Absolutely true. A little more expose can gain much more popularity. There always are a lot of competitors which really makes it much challenging for new projects to gain a firm position in the markets. Vouch copies from reputed members is always a better option for a headstart as you mentioned but mass promotion too might be something which is needed.
