If you are unhappy with what you have been offered you have all the freedom to reject the offer. There are many around who will be happy to take the job. If you intend to bring your wife here, you may be able to do so on a visit visa as your salary does not qualify you for a permanent resident visa for your wife. A visit visa is for just six months duration. Taking a house or an apartment even for a few months is going to cost you. As for the five years of experience you have this is not much compared to the experience the people have here in the job market who are looking for employment opportunities.
