Mr. Humpreet,
It's wonderful to see your website, it reflects the passion with which you have sustained your business over 3 decades.
Whenever you are associated with a product that is better than the regular ones, typically its price is also higher.. and therefore the buyer segment will also be different and need not be the regular set of buyers.
Create campaigns to reach out to these kind of buyers... It could be offline campaigns - highlighting the particular brand and its value and its variants that you have currently stocked in your inventory.
You could also adopt the online route, if you have already not ventured in this path... Most premium buyers go for the online retail approach of Amazon/Flipkart.. get your Brand listed there with offer and quick delivery... you will easily score faster than your competition!
All the best!
Cheers...
