Getting a buckled wheel to run true is not so easy but can be done. It takes careful shrinking of the appropriate spokes and maybe stretch others. It takes experience to get it right. I'm sure there will be places about over there that will do it for you.
Balancing: It won't be many posts before someone says to use Dynabeads (or whatever they are called over there). They are small bead that go in the tyre and automatically balanace the wheel as you drive. I haven't used them - I use an old free running front hub to mount the wheel and by trial and error, add weight to the top when the wheel stops moving till it stays where I put it (90° off where it stoped.)
