I gather that none of you are getting paid for the work you are doing. If so, the idea of each person being compensated for their time by sharing in the profit is workable and you don`t need to create any "phantom" stock to do that. As previously mentioned, using hours presumes that each hour from each person has the same value. Consider how you will feel about distributing (based upon your scenario) 1/3 of the profits to them if (when) the business is successful.
Over what time period do you intend for this to operate? ( forever, one year, until they have received a specific amount)?
If you want to discuss the details (in confidence) of your situation, feel free to send me a PM.
There really are several issues:
1. Fair compensation to each person for their efforts (time). You may have a difficult time paying everybody the "same" hourly rate.
2.Distributing the results of the business operations (profits)
3 Portion of the value of the company (ownership/equity)
4. Control of the direction and decisions.
In your scenario, you would be the only one who benefits from selling the company while the others could lose compensation. Also, the "deal" you have with your "employees" would likely deter any serious investors.
