Hi B.,
There is an excellent reason why you hate sticker charts...they don't really work in the long run. Many years ago (about 16) I came across an interview with a well-known educator, Alfie Kohn, discussing rewards and punishments. I looked up the interview (luckily, I found it on the internet, as it is easier than sending you my hardcopy). http://www.alfiekohn.org/teaching/pbracwak.htm
I have read much of his material and put the ideas to the test over the years. Thus, I can wholeheartedly recommed investigating his work and premises to others. My 15 year old son often shares with others his appreciation that I am willing to be "different" from other parents; from my point of view, I am delighted that he has a wonderfully compassionate heart and is always willing to help others and interact with all ages. My 11 year old is more of a challenge, but he also has a number of relatively minor learning/perceiving challenges as well. Still, he has a great heart and is kind and loving...and generally willingly helpful. He also agrees that the reward systems don't work for him--he just gets bored and irritated. Instead, I attempt to make the "chores" more enjoyable when we can do them together and/or have a lot of other positive activities, not necessarily related to what I ask him to do.
Both sons are home educated and are active in various activities and interests with others. We have 9 horses, 9 dwarf dairy goats (3 does we currently milk for family use), 40+ chickens, chicks, guinea keets, rabbit, dog, cats, fish, gerbil, etc. We ride horses, bikes, go hiking, garden, read a wide variety of materials, have lots of opportunity for creative (and necessary) hands on projects, and of course...lots of interaction with the animals. I teach riding and also train horses, dogs, etc., as well as do other work from our home, so I often need the boys to step in and lend a hand. They have great friends, who are often over at our place.
Best of luck and I really hope you find ideas that work well for your daughters and you.
