M&A Expert in London

My client is considering acquiring a Singapore based technology firm to advance his ecommerce initiative. The two sides are meeting imminently to discuss potential ways to partner. One option is for my client to acquire their company using cash and shares of a publicly traded company where he's the majority shareholder. The other is to partner on a specific project and pay with cash and equity shares in the project. Client could use experienced M&A professional based in London to advise him on the process and suggest the best structure for partnership.
