Extremely niche market feedback

Hello everyone.
Almost two weeks ago I published my B2B business intelligence service.
I recognise this is a very niche market to dive in, but I am determined in investing in this (at least in Italy) unsaturated market.
Recently I found a groundbreaking discovery that allowed me to lower my prices as low as possible (destroying the competition). Even italian ufficial sources can't offer my prices (that go as low as 1.99€ for a full report).
I immediately added this data and changed the plan, but here I am, still with no conversion at all despite hopping on ads campaign and SEO best practices.

What are your suggestion to make my service pop up and, more importantly, is it worth it for such a niche market?
