Tearing down a wall. Is it possible? How much?

[Srdjan Ilic]

Thank you for taking the the time to read and provide any feedback in advance. 

The house is about 1200 sq ft with a big wall/closet in the middle (see picture attached). The floors are nice so I don’t see the need to do anything there but I will need to tear down the wall or possibly create a window with counter or opening depending on what is involved with the process. 

I have done a cost analysis for repairs but I am not sure how much this part would cost or if/how I can do it. Please help and any recommendations in the Phoenix east mesa area would be appreciated.
