Saving in Maryland for a L1 visa

My company offers me package around 4000 usd/month post tax deduction and my proposed job location is Maryland. I would be given a L1 visa and planning to take my family with kid(3 yrs old). How much would I be able to save and how easy is to get a job for my spouse (completed mba finance in india and would be given L2 visa) ?? I currently earn 9l p.a out here?? Can I take this offer? Early response much appreciated ?
