looking for international student to stay for free in ASHENDON, Western Australia for sale

Hi I am a working mum and I have 2 children under the age of two. I mostly do night shifts and my partner does morning shifts and I am looking for an international student or anyone requiring accomodation to use my 1 bedroom for free in exchange for looking after my kids from 6 to 815 in the mornings and then 5 to 9 at night. I ussually finish work around 8 or so in the morning and go back to sleep in the evenings at 5pm. I live near the train station in Kelmscott, and its only 2 mins to the train station. NO BILLS, AT ALL. INTERNET WIRELESS IS AVAILABLE FOR NO CHARGE AT ALL. ALL I NEED IN RETURN from a trustworthy person and honest person IS HELP WITH MY KIDS IN THE MORNINGS AND EVENINGS. I prefer international students but also prefer any oner interested. will require police check and working with children check.
