Right hand man ? An assistant ?
How large an operation are you talking about where all this manpower is needed.
I ran the main grow for our local co-op for the last 2.5 years by myself,i ran 8 seperate 4ft x 8ft flood tables,took care of 16 strains of mothers in soil,took all cuttings & maintained the cloners,changed 8 seperate 55 gallon rez's every 10 days,maintained all ph levels as well as nutrient levels ect.
The only time i needed help was one day a week to harvest a table & trim,while the trimmers were at work i would clean & restock the table,the harvest day myself & 3 other people trimming worked 7 to 10 hours,the other 6 days i spent between 2 to 4 hours a day maintaining the op.
If your going hydroponic i can show you how to stream line & automate the system so all you need to do is flip a switch to drain the rez's right into the buildings waste water lines & turn a lever to refill the rez's.
Anyhow about compensation,you should be compensated according to the amount you grow not hours spent,a fair amount would be 5% to 10% of the resale value of the product you grow for them,paying in percentages gives the grower incentive to produce more & better quality.
A typical 4 x 8 flood table should pull right about 5 lbs at harvest,at a club price of $10 a gram your looking at $23,000 per table on their end, every week,,i'd be dammed if i put that kinda profits in anybodys pocket for less than 5% to start,once shit got really poppin i would want the full 10%.
Dont be in a hurry to take their offer if it isnt large,i was a part owner of a co-op & i know 1st hand how much profit even the smallest clubs are pulling in,the figures are staggering,get your fair share,without the grower all they have is a building,remember one thing,they asked you so that means they need you right now but most likely that wont last,every club i know about allways ends up having family do the growing once they learn how & the pro grower is given the boot so make sure you get all you can.
