How can I raise money to meet my grandfather?

[AnnoyedCousin]

I never meet my grandfather before and it costs $700 dollars to go and see him. I never talked to him in real or on phone. I want to meet him before i graduate from high school. My parents don't have the money to go down and see him so i have to pay four all four of us (my step-dad, my mom, my sister, and me) to go down and that is $700 dollars all together. I cant get a job under june at least. I do have my cpr training so i can babysit and i been looking for a babysitting job but no one that i asked needed one and no one called from the flyers. Any ideas as to how i can raise it?
I havent talked to my grandfather before because my mom doesnt like him so she wont let me but i finally got her to agree to go down and see him before he passes away since he is 74 and all
no illegal things please
