MPK Freight

I would like to know the following:
1] How can a company like MPK Freight, from Blantyre, MALAWI become one of your members and promote the route? If there are costs, how much?
2] What are some of the benefits of using Walvis Bay for imports into Malawi from the West-Side of the planet [Brazil, USA, etc]?
3] Are you in a position to recommend Freight Forwarding Agents who we can be working with to promote traders using this route?

Waiting for you feedback.
