That would be Advantage Solutions. They are a merchandising company that hires employees, not independent contractors, so if you sign up with them and are hired you will be given a schedule, you don't get to pick your assignments usually (though unless it is date and time specific work you may have flexibility on when you can go). Probably the person who has the display on her schedule is not allowed to make more than a certain amount of visits per month or she would likely do them more often. Not her fault, blame it on the company.
