scuba diving gear for aScience Teacher

Hello everyone. I'm a science teacher at a high school in my hometown. I dive for about three years but unfortunately all the time with equipment that does not belong to me, leased equipment. I keep trying to attract students to engage in this particular field. Unfortunately it's hard to live with a salary of a teacher in Israel. It also makes it very hard for me to buy scuba diving equipment that I really want. I would be happy if you can help raising the money needed to purchase ascuba diving equipment thet i need.
