Site Structure Design for a Manufacturing Company

I am in the process of setting up a website for one of our 3 companies based in Africa.

We are manufacturers of Polyethylene pipe, tarpaulin for crop covers and tents as well as suppliers of Treadle pumps, we are based in Mozambique, Botswana and Malawi.

We need someone who is very experienced in site structure design to help us design our new website site structure. This should be designed with SEO, usability, best practice and the customer in mind.

In particular we need help with our products section and how to best structure this based on the varied product range that we have, this would require you to research our products based on the materials be provide as well as various similar websites and make a call on how best to structure this, we basically have 3 main lines of products and an idea of how it might be structured below:

Pipe > including Polyethylene Pipe (various products for various uses) and PVC pipe (various products various uses) –structured by product or use for example.

Tarpaulins & Tents > various products and uses, structured by product or use for example.

Treadle pumps > various products and uses, structured by product or use for example.

This might require further thought on the general grouping etc.

I would require a fairly detailed wireframe so I could literally take the next steps of how to populate the structure with content and a clear understanding of what content would be required.

Look forward to hearing from you.
