Keep in mind working almost every day after work for minimum wage will have you working twice or three times as much and you'll be making less; however, this will look better on resumes for future jobs.
mow lawns in the spring/summer, rake leaves in the fall, and shovel drive ways in the winter. Very easy ways to make a ton of money with a lot less work than people have to much "pride" to do. Realistically, they are lazy morons.
Using this idea I made enough money to fuel my paintball hobby, bought my first and second car with cash each over $3000, kept up with maintenance on them, went to family things like worlds of fun, six flags etc., and had a little set back to use while going to my tech school in another state.
lol sounds like you are making a living on yardwork.
