Hi Sara,
How are you doing? I received your letter regarding babysitting and prices for one hour service. Unfortunately, I will not be able to babysit on coming Saturday as I have an urgent meeting with my groupmates at the university. We are working on a presentation together and weekend is the only day when all students are free. Moreover, as deadline is next Monday we have to complete it during weekend. I am very sorry that I cannot help you with this on this weekend. However, I will be available next weekend if you still need a babysitter. I charge 20 US dollars per hour and transportation fee is included to it. Please let me know if you want me to come next weekend.
Take care.
Mila.
