"Sales today is more about education, rather than promotion",
It is a huge milestone for any business to have it's own sales page, infact being in a need of a sales page is an achievement in itself.
"This is exactly what I am looking for!", should be the reaction of the customer visiting your promotion platform. Several times it happens that the customer may not understand your products and services even if it were exactly what he or she was looking for.
Sometimes customers end up being unsatisfied because of many reasons like:
1. Information not being enough for someone to comprehend
2. Too much eagerness to sell your products
3. Insufficient services
4. Not a worthwhile experience of the platform
All these issues that businesses, like that of yours, face could majorly be due to an inadequate sales page or even the absence of a sales page.
Finance Businesses should have a sales page, and I think you realize that, otherwise why would people trust you with their money? Barack Obama once said, "Money is not the only answer, but it makes a difference", and just look at his financial conditions.
Lastly, I would like to point out that all the 'bid description' that you encounter on this project are nothing but sales pages in their core.
