Custom square baling

New to the page and new to custom harvesting. I found an ad on Craigslist, some guy needed his fields fully processed. Got a hold of him and went to take a look at the fields. About 10 acres total right in front of the barn. We settled on a price but after doing some research it seams I have undercut myself a bit. I'm going to be cutting teding raking and baling for a total of $1.40 per bale. I know this is low and I need to work on pricing but for this time I'm going with it. My question here is what do I charge to stack the hay in his barn? The barn is 100 yards from the field. Easy in and out, I can pull wagon in one side and pull straight out the other. Would like to make some money back from under cutting myself especially because I'll have to pay people to stack. The land owner is old and can't move hay around well. Also tips on pricing would be appreciated.
