Re: apple Pollination
The service you are providing is installing and removing your hives when the grower wants them. No difference whether they are on site for two weeks of four. It's the placing and removing that you are getting paid for, besides the colonies being up to the job.
So, I would quote a price for the term of placement no matter how long or short a period of time that is.
I recall one year that I put hives in apple orchards in NY and then took off for SC to get the rest of my bees only to get a call that the orchards wanted them out when I got down into PA, 1/4 the way there, one week after putting them in the orchards. So I went back and pulled them out.
Don't argue w/ your grower, just stick to a price worthwhile to you. Other than that one time my hives are usually in apples for three weeks or more. From the time the King Blossom opens until the last petal hits the ground.
How experienced is your grower? How big an orchard? What kind of apples? Are they some special variety that doesn't have a long bloom period? Not that any of that is really your concern. The apple grower wants bees and you want to get paid to put them in when he wants them and then take them out when he wants them out. That's how I look at it.
