Doing some research on Google I have found these suppliers of SEO services who are based in Teesside, rather than just ranking for the search term and created a small directory.
Some Teesside resources, from Middlesbrough, Stockton on Tees, Redcar, Hartlepool and further afield. Where local SEO news and features relate to the Teesside area. It is located in the North east of England, mainly off the A19 road going North and South and A66 that comes from the west. With an industrial history it now houses some great IT specialists, especially those than have passed through the Middlesbrough University.
