You can come on a visit visa, and do visa runs after it expires if  you don't find work.  You cannot apply for a "permanent" visa - your employer provides the work visa and helps with residency - you can't do that on your own.

It is an expensive place to live if you have no income, you can't rent a "regular" flat as you don't have residency so it would have to be a hotel apartment.  You can drive on your country's driver's license for (I think) 10 days - no longer in a rented car, you can't buy a car and get it registered without residency.

You've only been looking for 4 weeks - that's not a long time in this part of the world.  Keep trying.  If you can afford to, send hubby ahead to try and find something.  If you can't, don't
