Here's what I do:
To find eligible candidates, if I know someone or know someone who may know someone, start from there. Otherwise post a flier (i.e. in some online job board).
At interview, ask about educational background and career, but tell nothing about the equity offer. If you find the possible candidate then give him more (safe) information about your business. Let's see if he get interested or not (if he is, he asks for more information). Highlight your lack of business administration knowledge and experience. Finally ask what is his expected salary as CEO (you better do this in separate meetings, not at once). Whatever he asked for salary, tell him although you are very interested to work with him but currently you cannot pay such salary. Key point is, if he suggests other privileges (equity) in return to some guaranteed output, he's probably the right person. If he is going to work at low rate (based on resume and market wage ranges) and guarantee that for example at one year he rises profit to 20% or more then there are two points:
- He is going to take risk like other co-founders and behind this, you
know he has seen some potentiality which you didn't.
- He is so sure about his ability to make effective changes that
is going to guarantee (with some estimate) a specific measurable
You can write an agreement to give up some equity upon he meets his claim (you can split it in more than one step) but keep VETO power for yourself on his business decisions because he may go to get what has promised in exchange to ruin (usually at long-term) something more valuable i.e. customer loyalty, company reputation...
This may not be easy to implement but he is gonna join you as co-founder so it worth to do it as good as possible: A clever person solves a problem. A wise person avoids it.
There is much more on this but enough to transfer the concept, let me know if something is unclear to you.
Here is a list of top executives in large businesses and governments who have worked for an annual salary of 1$ (It is not a good idea to make such offer to your new partner!)
