Having an Orthodox conversion to Judaism ?

I had a Conservative conversion to Judaism quite a few years ago, but now I'm at the point where its become an issue because my husband (who was born Jewish) and I would like to immigrate to Israel and would also like to have a first baby. I'd like the baby to be seen as Jewish by all branches, I'd like to be seen like that myself as well. About how long would it take to have an Orthodox conversion if I've already done this and I've been actively practicing Judaism for years? I also want to make sure the conversion will be accepted by the Rabbinical authorities in Israel, where would i find an up to date list of "approved rabbis"? Can people who are really Jewish please answer.
