Helping realtors sell homes...your opinion

What do you think of this business idea...Deliverying flyers in plastic bag door to door for multiple realtors. Each bag would contain the flyer advertising a home for sale, open houses, price changes, etc. More than one realtor ad per bag, so if I have 10 realtors' ads in one bad and deliver to 1,000 homes, that $1,000 for approximately 16 hours of work. I have summer off, just looking for extra $ and exercise.
One summer I delivered for 1 realtor at a time...very time consuming but charged 15 cents per flyer.
This would give the homes extra exposure . Any thoughts.
