Can I build an electrical pole structure to hold a power wire into my property?
Check with your utility to see if they have a program to bury your service line.  My company (FPL) has a program where they will give you the conduit to bury along with instructions.  Once everything is set up and meets their standards, they will bring the lines down the pole for you.  There is a fee, of course.  For FPL in my area, it would cost around $580 plus the cost of an electrician (and permits) you must hire to rearrange the meter.
