Can we survive in Czech Republic?

Hi, thanks for viewing my question. Well my husband and I are going to be moving to czech fairly soon and he is a mechanic here in the US and wants to continue to do the same in Czech as he is also basically a fluent speaker. I would like to know do you think we could live off his income alone in czech as we would like to have children there and I would love to stay at home or do work for a church in prauge. Should we save money here in the US then when we go to convert the money it is alot of czech money? What should we do about jobs. Oh, and I barely know any czech. How long do you think it will take a mechanic with a college degree and 10 years mechanic experience to find a job? I know we wont have the m luxury here like we do in the US but my husband desperately is being called to his home land even though he is a US citizen. Thanks! Any answers or advice would be GREATLY appreciated! :)
