Deep Dive Market Research on Competitors

We are a data compilation and marketing services provider that specializes in the B2B K-12 educational marketing and data space. We have two major competitors - but over the last few years a number of secondary competitors have jumped on to the scene - we want to better understand what and where the market is heading and who offers what - and - how they compare to us. We would like to hire someone to do some in-depth market research on all of these competitors - about 10 competitive companies in total. We have obviously already reviewed their websites - so we need a deeper dive than this. We need a more detailed personal interactions undertaken by a neutral - independent party looking at each with a case study opportunity. We need a secret shopper experience type deep dive to better understand pricing - services - how they position - sample data to review - counts and coverage. The provider needs to be US based - and have a actual profile on Linkedin - etc - that would make the exploration legitimate so they can be fully transparent. While we would not have anyone misrepresent anything - we are looking for someone that present this as a customer that is in the market and looking to better to understand the vendor space and what they offer - etc.
