Hiring a faculty consultant We need to hire a computer scientist with a very particular specialty as a consultant for a long term industrial research project.  We've read the relevant papers and so know who does good work in it.  But we don't know the first thing about hiring a professor as a consultant.


Do I just email them and say "Hi, Dr. So and so, I've read your paper about X and want to discuss hiring you as a consultant"? Or do I need some type of introduction?  Specifically, if I'm coming from a small business (with the funds to hire them, mind you, but a small business nonetheless), will they take it seriously?
How can I evaluate their abilities to be a good consultant? I know they have the brains and the know-how, but I need more than that: I need someone who will work on the problems we have, giving us a reasonable assessment of their likelihood to solve them, keeping us up to date, and clearing communicating their results.
Once hired, how do we effectively manage them towards our goals?
Currently, we have funding to hire them only for the initial stages. With good results, we have investors to approach, and we'd like to say "We're working on this problem; we have Prof. X on it, who's done this so far; with another $1M, we could get here." Will academics be supportive of such an arrangement?
How do we protect our intellectual property? Our plan is to leverage existing research towards new technological applications.  What's to stop our consultants from taking our ideas on their own? This is especially a concern in the initial evaluation stages, where we don't have a business relationship, but need to discuss our applications in some detail nonetheless.


Finally: Are there any resources on how to do this? Books, articles, services? We'd really like to benefit from someone's experience on this.
As an academic with a history of consulting, the proper way to approach the person in question is to contact him directly. Email might work but for initial contacts phone might be better. If he/she is geographically close, a face-to-face would be even better. The initial conversation is really about whether he/she is interested in consulting in his/her area of expertise. If yes, then you can start to dig a little deeper into the project.

Be clear and up front with what you have and what you hope to achieve. Make it clear what the limitations of the project are and that the project might or might not move past the initial phase.

It is unlikely that the size of your business would be an issue but that really depends on his/her personality. You'll know when you ask.

About evaluating if he/she can be a good consultant, explain very clearly what your concerns are. There is no reason for the Prof to be concerned since you do not know each other there is not an issue of personalities and you are not doubting him/her, you are simply saying what you are concerned about. If you have read this person's work you should have an idea of his/her ability to communicate clearly.

As far as managing this person toward the goal, handle him/her as you would any other employee. Normally consultants expect a little bit more freedom but, to repeat myself, be clear with what you want and that might include an update every 2-3 days (more or less depending on the nature of the project - you might want daily updates).

As for protecting your intellectual property, have the Prof sign an NDA/non-compete. This might be an issue if it will in any way limit the Prof from exploring his/her own work. For this, you will need to negotiate what kind of legal protections you feel you need. If you write the non-compete in a narrow enough way, the Prof might feel comfortable enough (he/she is getting something out of the deal).
