Any advice on selling to government contractors

I’m a data scientist at the UK Government’s Department for Energy Security and Net Zero, and I’ve seen firsthand how messy project management can get—billion-dollar portfolios being run on spreadsheets and siloed data. It’s a nightmare.

I’m working on a solution to fix this and want to reach out to contractors. Anybody has done this before? Where to find the contractors and what’s the best way to reach out to them?
