Since you would still like to have your privacy (and I cannot blame you OP), then a full-time nanny is the best option for your situation.
The hours are doable and while there are some nannies that wouldn't take a job w/a parent who is working in the home, there are some who would consider it so if I were you, I would start the process as soon as you can.
I want to give you some advice as I have been a nanny that has worked alongside a parent who telecommutes.
It is a challenge for the nanny since the children always behave differently when they know Mom is still in the house. It totally changes the dynamic for everyone and to make this situation a win-win for everyone involved it would be best if you stayed out of the way as much as possible.
If I were you, I would encourage the nanny to take your children out of the house often and take daily outings. When in the home, make sure you focus entirely on your workload and let the nanny focus on hers. It may be tough hearing your child cry in another part of the house and it will also be tempting to interfere if you feel the nanny is not doing something the way you would, but nothing will make this situation fail worse than micromanagement, trust me.
All in all, I wish you the best of luck in your search for your dream Nanny!
