You can visit this site to view a listing of working from home opportunities. A lot of them have to do with "guest-writing" on someone else's blog but there are other kinds of job postings their as well. The site will tell you how much the employer has in the way of a budget - how much they are willing to pay you.
If you are interested in the job posting you can make a "bid" on it and if it is accepted then you and the employer can come to terms.
