You can only obtain legitimate work from home positions from brick and mortar companies. You want to send your resume out to companies hiring for positions you are qualified for, but include in your resume that you have a home office and you wish to work remotely. Include how you have your home office set up and what equipment you already have in order for you to perform your job. These jobs are just going to advertised as jobs, they would not promote them as work at home because they would hear from too many unqualified people
most people built a website, and they earn from many advertisement, and some of them earn some commission from sales on their website.
