It's hard to appraise your work. Either your freelance hourprice or the price of your "packaged deal", I think the only wise thing to do is ask yourself: "what would I pay for it if someone else did the job for me?"

Of course, if your product or service is aimed at large companies you can try to sell it for twice as much as you normally would, but that's about it.

Another thing to keep in mind is that you have to make a living. Don't sell your services or products for too little, since you have to pay your own bills. But that's probably too obvious to mention...
