Travel expenses for a medical mission to Honduras

My name is Evelyn. I'm a Registered Nurse volunteering to go on a medical mission to Honduras in September with One World Surgery. I will be dedicating a week of my time to help underprivileged people receive both eye and orthopedic surgery. Without the organization and volunteers thee people would not be able to receive these services. However this also comes at a cost to volunteers for travel expenses and for participating in the program since part of the cost also goes towards supplies and expenses to run the surgical center. Any help would be greatly appreciated to help fulfill this lifelong humbling dream of helping people which comes as second nature to being a nurse. Thanks everyone!
