ISO house cleaner - I am putting my house on the market and need a "deep cleaning" done (have been renovating and there is dust everywhere), but will also need upkeep because I work rotating shifts and will need to accommodate realtor showings...mainly dusting and vacuuming/mopping. Any recommendations? Need someone who can be flexible on days/times. If I am happy with your work, I may continue using services for my new house. (Turners Falls area)
