Farmers in a certain area grow a type of vegetable, A, with an annual production cost of 7000 yuan per acre. The yield and price of vegetable A per acre are influenced by both weather and market conditions. It is predicted that the probability of normal rainfall next year is $\frac{2}{3}$, and the probability of less rainfall is $\frac{1}{3}$. If the rainfall is normal, the probability that the yield of vegetable A is 2000 kg per acre and the price is 6 yuan/kg is $\frac{1}{4}$, and the probability that the price is 3 yuan/kg is $\frac{3}{4}$. If the rainfall is less, the yield of vegetable A is 1500 kg per acre, the probability that the price is 6 yuan/kg is $\frac{2}{3}$, and the probability that the price is 3 yuan/kg is $\frac{1}{3}$.
(1) Calculate the probability that farmers growing vegetable A will not lose money next year;
(2) Under government guidance, it is planned to adopt a "company plus farmers, order agriculture" production model next year. A company will invest in building greenhouses for farmers without increasing their production costs. After building the greenhouses, the yield is not affected by the weather, so the yield per acre is 2500 kg. All the vegetables produced by the farmers will be purchased by the company. To ensure that the farmers' expected income per acre increases by 1000 yuan, what is the minimum purchase price?
