Looking For Cleaner 3-4 Hours Bi-weekly

I'm aiming to keep cleaning to whatever can be accomplished in 3-4 hours every other week to start. I am interested in help cleaning the bathrooms and first floor (dusting, vacuuming, mopping as time allows). I like to clean but my house is large, my husband and I work full time, and we have two kids (4 and 7 years old) and keeping up with cleaning is a challenge. If I find this work helpful, I may be interested in increasing the hours or moving to every week or occasional deep cleaning. I plan to pick up before you'd arrive so that you could focus on cleaning and not tidying, but you may need to dust around busy shelves/mantles etc. The first floor is where we spend most of our time and includes a kitchen, dining room, family room, and large foyer with reading room. If you read this description, include the word purple in your response.
