Housekeeper and Home Cook Needed

We live on campus in couples graduate housing, and as two busy PhD students are looking for help around the house. We are looking for someone who can work 2 days a week, for 3 hours each day, $18/hour. Exact hours are flexible.

We would like help with:

General home cleaning
Laundry
Tidying and organizing
Making a basic meal (soups, etc) from a provided recipe and ingredients

Requirements:
Housecleaning experience
Ability to work quickly and efficiently
Comfortable receiving feedback
Ability to do basic cooking
Willing to run occasional errands, such as dry cleaning and grocery shopping
Need own transportation
Reliability and stability
At least two references

We have had three different assistants in the past year, so our biggest concern is stability, knowing that you will be able to keep the position and are not just in-between jobs, moving soon, etc.
