Paul the Painter was contacted by Helen Homeowner regarding the painting of Ms. Homeowner's two-story home. She asked Mr. Painter to come to her home to look over the house and provide her with an estimate for the cost of painting the entire exterior of the home. Mr. Painter gave Ms. Homeowner a written estimate. Ms. Homeowner stated that she would like to have Mr. Painter to paint her home in two weeks from the date of the estimate.Mr. Painter then went out and purchased the paint supplies and other materials to complete the job. During the course of the two weeks, Mr. Painter and Ms. Homeowner discussed the performance and that everything was still on. The day before, Ms. Homeowner told Mr. Painter that she changed her mind. Mr. Painter advised that he was going to sue Ms. Homeowner for breach of contract as he had already purchased all of the materials for the job. Does Mr. Painter have a legal claim against Ms. Homeowner?

your task is to draft arguments that Ms. Homeowner should not have to pay Mr. Painter for the cost of painting her home and does not have a claim against Ms. Homeowner for breach of contract.
