I think that is one of my problem.I told the parents inquiring that I just opened and I don't have clients yet.I told them about my price too over the phone.Someone told me not to tell my price over the phone.I should invite them first and discuss it personally.Actually the $600-700 price is for full time service and it is from 7:00-5:30pm.,Monday to Friday..I am very thankful that I joined this site and I was able to learned a lot from you guys.Thank you for your advice.
