In search of opportunities for self employment of a Computer Engineer?

I think the best would do something like developing applications for the iPhone or Android. This may include some custom hardware interface for phones / too many tablets as they have good electrical skills base.

There are also

Plenty of opportunities to develop their own software / web company. The income potential is virtually unlimited (the birds angry or ebay), but it will be very inconsistent, so you would probably like some kind of "sugar mama" with a steady job.

If you are thinking

Have some kind of private practice / consulting firm, I've never heard of such thing as computer engineers. It may be possible with a small group of engineers from a variety of fields.
