With this year’s festivities expected to once again bring in thousands, entrepreneurs have stepped into the line-sitting business. InLine4You LLC, an Omaha-based service, says it has more than 40 reservations for sitters, who will show up at a requested time and stand in line on behalf of a meeting attendee, up from five last year. The service costs $110, including $50 for InLine4You and $60 for the line sitter, said company founder Darren Hromadka.
