That's peanuts. I would no way consider making models for anyone for that little money.
Volume, volume... sell cheap but by the thousands. I wouldn't do that either for $10 if it would be contract work sold with all rights to some single person. But if you sell five of them it's $50 and that sounds better. Getting only 10$ would mean that I'd have do it in 20 minutes, modeling, textures & mapping included to make a decent pay per hour - not possible.
And I also wonder why people think your house is expensive - those without the skills to do even simple model like that would struggle for DAYS to create even half as good model... compared that they could get it instantly for $10. Time is money and all that.
