Help bring Miriam and Estella to Canada

We are hoping to bring a mother and daughter to Canada for a month in the summer to show her the sites of Western Canada and hope that they can see themselves here to further Estella's education.  In Belize, most children only finish elementary school.  The average income of families in Belize is low, it is a struggle to put food on the table let alone pay for education.  Most Belizeans are employed in the tourism industry that is seasonal, there are times when they have little to no income.  Education is a luxury most can not afford.  We have known this family for 10 years, we would love to have Estella stay with us and further her education in Canada.
Thank you
