We have been workamper subscribers for 3 years. We have never applied to a job we saw in the ads, but, we have received several job offers because of our resume that is posted. That bad part - the job offers were always from campgrounds that have poor reviews from prior workers, or it's for summer in the south or too far north in the fall/winter.
As far as earning at least $1,000 per month, that could be difficult unless you work full time with all hours paid, and most positions pay somewhere around minimum wage. There are some long term jobs posted that are for management positions with better pay. It's just not what we are looking for yet. We aren't ready to stay in the same place for at least a year.
