Moving to the USA .

Hi,
   I have a few questions I hope some one can help me with ..I married an American citizen in new York on the 23/12/2009 she then moved the UK , after a few years we decided that we would all move to the USA as she was not really settled and there were illnesses in the family .She moved there roughly October 2013 , I have 2 children 1 x 15 year old and 1 x 13 year old ..My questions are !!
1) Has anyone done this and if so what visa did they use ?
2) do you know the best websites pages to use for applying for visas ?
3) roughly how much did the visas cost ?..

Many Thanks in advance .
