Although I do some work for the poeple who's land I hunt on.....i made those arrangements AFTER I already had access. I can see how, in some instances, offering to help would aid you get said access. If you think that'll help....by all means use it. I just think that the gesture is more genuine when you're not trying to get something from them. It seems to me to mean more when it's a true gesture......and not a trade. I'm sure the trade-off system works, though.
