Question of GTM Tools

Hi all,
My company is looking for a consultant who has turned early, top-of-funnel interest into paying signups for early-stage B2B SaaS companies. We looking to market our new product line that sells AI-created expert systems for transactional document creation into the financial services and insurance verticals. The AI does the building, and the client's domain experts guide the AI and validate/refine the resulting system.
Our GTM awareness engine is working. Since July 1 we've generated over 1,200 website visitors, nearly 200 companies engaged and in contact with us through cold outreach, and over 1,500 LinkedIn impressions on our posts.
Our challenge is conversion - we need help turning the interest we're generating into companies that sign up for Free Trial accounts on the service.
We're looking for a consultant to help us diagnose where prospects drop off between first touch and signup and guide us on tightening our offers, calls to action, and signup paths.
We'd like to find someone with a track record of converting early pipeline into signups at a seed to Series B B2B SaaS company who can help us with hands-on efforts, not just strategy, and is open to a contracted consulting engagement. We'd ideally like to find someone with experience selling into regulated buyers (financial services, insurance, retirement plans).

If anyone knows of a consultant or company that provides this kind of service, I'd love to hear about it. Thanks.
