Looking to hire a consultant with expertise in Brexit

I am looking to hire a consultant with expertise in Brexit to help me with a specific trade issue. My desired outcome would be to gain a better understanding of the complexities and nuances of international trade, and how I could proactively manage this complexity in my own business.

I would prefer a consultant who is knowledgeable in issues surrounding trade and tariffs, immigration and visas, and regulatory compliance, specifically in relation to Brexit. Furthermore, I would like a consultant who can provide technical advice and strategic guidance on navigating Brexit-related issues.

I would like to engage with the consultant primarily via email to ensure that all questions can be thoroughly answered and discussed in a comprehensive manner. If there is a point where phone call or video conference is the more focal communication option, the consultant must be comfortable employing either of these methods.
