Shopify partner agency research

I need some research into the top rated SHOPIFY digital agencies - those that are Shopify Premium or Platinum rated and based in the UK and USA. The research will need to list the name, address, phone number and web domain of each business, along with 5 high level business contacts at these agencies, to enable us to start outreach. The designations should be Directors/Head of Commercial/partnerships/client solutions/CEO/MD and we would like to have the linkedin profile and email/phone number of each person.

We would like the top 500 rated agencies in the UK and USA

Please provide an estimate cost and timeline
