*** I strongly advise that you sign a service provider agreement regardless of who you use, and I would be happy to give you some pointers on key things that you need to do in order to make sure that the project is completed to your satisfaction. I've drafted tens of these contracts for both sides (startups and service providers) and know exactly what they should include.
I've successfully helped over 300 entrepreneurs and would be happy to help you. After scheduling a call, be sure to please send me some background information so that I can prepare before - thus giving you maximum value for your money during the call itself.
If you're looking for a company that can help you with consulting on your DevOps I can refer you to a few options that I have personally worked with and are excellent.
I'm based in Silicon Valley, the heart of innovation, and have helped many companies build their products with either outsourced engineering or with firms that consult on your internal engineering teams. Feel free to call if this is helpful.
