Thailand school and conservation

my husband and I are looking to raise money to go volunteer in Thailand for 3 weeks to help at an animal conservatory and a few local schools. We will be helping to teach the children English, a tool that will make them extremely likely to make a successful living later in life in Thailands tourism industry. We will also be helping at an animal conservatory which primarily helps save elephants that have had hard and cruel lives, but it also helps protect a variety of endangered animals in the area. we have wanted to do this for a few years now and are looking to raise money so that we may finally be able to reach our goal!
