Hastings to london can anyone help ?

I always go on holiday in the uk, on these occasions i can get a weeks bus ticket and go quite far on it, in Llandudno i can get a ticket that takes me all the to Liverpool, Great yarmouth's tickets get me as far as norwich, but i seem to be having trouble finding a bus company that goes quite far away from Hastings does anyone know any ? or is there a weekly train ticket that is the same as a bus ticket so i can go anywhere.
