I own and run a self-publishing business for the last 2 years with a turnover of $120k. Whilst in the industry I became frustrated with the lack of good and timely information from Amazon, their data was presented in an extremely crude format and I have seen an opportunity to create a sales and PPC ad dashboard to collate all of the data into one place and allow authors and publishers to make better decisions on their marketing through better data.

The initial design has been started with a team, but I feel I am lacking the knowledge (and certainly experience to know a 'blueprint' or the next stages and evolution of creating a SaaS. What are the most efficient next steps? Where should I be spending most of my time?
