Nanny Needed For My Children - Full-time / Part-time

We are looking for a great nanny for 2 children in Eugene. We would prefer someone who could help out with light housekeeping and preparing simple dinners. This is a full time job (40 hours / week) that will last 4-6 weeks while I recover from surgery. I don't have the exact surgery date yet but it will be sometime this fall and we would like to make arrangements in advance. We would love to find someone who speaks Spanish, but it's not necessary.
