These are companies that I have worked with and or my clients have worked with successfully over the years. Consider this a starting point to your search for qualified contacts you may need for various work.

You should conduct your own independent investigation of these contacts and draw your own conclusions. As you would do with any other person you would hire, you should call several and ask them what the scope of their service will include. Do they have liability, errors, and omissions insurance? What is the scope of their work and what does it include and any other question you deem fit.
