Based on the details mentioned by you it seems that you want to break the status-quo of your business. I would advise you to revisit your business model than just looking at enhancing sales. That means, you should pen-down your top 3 business problems/challenges, analyze modern technology and platforms that could be leveraged, and map your business with appropriate solution (s).

Larger part of above exercise will be to develop an "Integrated Growth Plan" with monetization enhancement as the hub. Do ensure not to just look at "Sales" number as the problem as well as solution. That may end you up with burning too much capital for too many things with too little solutioning potential.

In my decade of experience working with entrepreneurs I've seen people often confusing symptom to a disease, only to cure the symptom and let disease prevail.

Hope above helps!! All the best!! Need to discuss anything further? I am just a clarity away.
