will i be able to relocate to another state if i have a good job offer?

Even if you are awarded full custody, that doesn't necessarily give you the right to go out of state and essentially take the baby away from her mother, unless there is abuse going on- in which case you should ALREADY have custody. As long as there is no abuse going on, work out a custody agreement that gives you shared legal custody with the mother, and gives her full physical custody and gives you liberal visitation rights. Then go out of state and find a job- you need to support yourself and your baby.  But unless there is abuse going on, you can't possibly expect to get custody AND move out of state and take the baby away from her mother.
