Sometimes a solution requires expertise in a different field, or sometimes just a fresh viewpoint. Over the years, we have developed working relationships with a number of companies to broaden our offerings. Sadly, a lot of those companies have moved on, shut down, or been merged into others. 

Currently I subcontract a lot with T4BI (website) - a company based in Vancouver. They are extremely knowledgeable, fair, and honest. I would not hesitate to recommend them.
