earning money with Cottage Living?

I'm doing the millionaire scenario with a Sim who lives in Henford-on-Bagley & it's taken a while but she's doing pretty well. She started off with a cow & some chickens & started a garden. She also took the gardening career, specialising in the florist branch. I saved her rewards points until she had enough for a Money Tree & I planted the first few seeds that grew on the original tree - I think she has 12 planted now & so she gets a big lump of cash from them now. She also managed to get a golden chicken & that turned all her plants into perfect specimens. All of her flower arrangements get listed on Plopsy & have found that they sell really well on there - anything up to 20,000 Simoleans, even the wilted ones. When her first cow died she got a llama & she now has another cow after the llama died. She has reached the top of the gardening career so her pay is high. She's well over halfway to becoming a millionaire & I've enjoyed playing her.
