How can I hybridize tomatoes?

I am trying to make a "super tomato" that grows fast with large sweet juicy fruit, and is a hybrid of a roma, big boy, and early girl (Also possibly a siberian tomato)
I think I should cross pollinate the roma and big boy and then hybridize the seed from the hybridization with the early girl but I'm not positive someone please tell me how to do this.
