Well, I'm not for sale. But you can lease me. What do you need me for? Whatever it is, I can probably do it, or figure something out.
Cost depends on what it is you want me to do.
Things I'll do? yardwork, cleaning, manual labor. There's all sorts of stuff I could do. Use your imagination. If you could have a slave for a day, what would you want them to do?
Disclaimer: I won't do anything illegal. I probably won't do anything that will cause me pain. It's not likely I will do anything too humiliating, but ya never know if the price is right. I probably won't do anything that causes others unwilling pain either. That usually falls under the illegal part.
