Babysitter Needed for my Children - Full-time / Part-time

We need a nanny for our twin boys in Houston. We do have dog but is very friendly and generally out of the way. My wife and I work from home so we will be in an office working while you are in the playroom. We can easily help out if things get messy or the babies get too fussy. We are in Houston for about a month helping out family, so the position will only be during the month of August and into early September.
