all four wheels locked up no movement in any gear

Two weeks ago I was driving and my CV axle came loose. we bolted it back on but the next day it came out and fluid went every where and the caliper was bad. I got a new caliper and pads put them on. I then got a new CV axle and put it on. we bled the brakes all four tires and nothing. today I changed the master cylinder and still nothing. I am a single mom and doing all the work myself including pulling the parts. help! what is next. I need it to move.
