Landscaper Job - Little Falls, GP, 1724

I need to have my front garden lawn area leveled as we renovated a few years back and with the up and down of the vehicles the ground became uneven and it seems to be getting worse as I don't think that the ground was compacted correctly initially. I also need ideas on what to do in the backyard as there is an empty space behind a retainer wall. Lastly I need help with my sad flower beds, small side area and an area in the front.
