Help me reunite with my son n go to his graduation

My son, Zachary Westgate is now a senior in high school and he graduates this year. Zachary lives far away in another state and We haven't seen him in person in over 7 years. My daughter hasn't seen her brother since she was very little. We are trying to plan a trip out to see him graduate high school but the finances are just not available. I miss my son so very much and seeing him graduate high school is seriously a once in a lifetime opportunity. Please consider helping me get to my son. Thank you in advance.
