If you want the kudos of a degree, and the feeling of satisfaction of a job well done, then why not write your dissertation yourself? That way you will know that it meets your quality standards and if it doesn't you will only have yourself to blame.
It makes me laugh to see students posting about all the research they are doing to find the right company to write their papers or dissertations. If they spent that time doing their own research and writing their own papers then they would have more money in their pocket and have their self-respect intact.
Wake up and smell the coffee. Cheats deserve to be conned. It's called karma.
