I faced the same problem. I took my wife under another company visa and faced some problems. Luckily I got a chance to change my wife's sponsorship.

My advice for you is, please you come alone here and settle your self.No need much time for it. Just til u find a job.once u get a job, since u planing for Project management job, you may get entitle for the Family visa status.(Salary wise and Profession wise) so u can sponsor your wife (So she will be under your sponsorship) So she will be free as a bird. any time can work not happy then she can change the job.

This will give you the happiness u looking.

BUT this family visa process is bit long. minimum will take 3-6 months. So til that u can bring your wife under 6 months visit visa if u really need her to be with u before 6 months.

Hope this will help you to decide.
