I know as a designer as well many people charge extremely cheap prices at around $40-80 and it is irritating. But I also found that if you produce a quality service in the end you will be hired. I still get clients at the range of $300/per project whereas I've seen designers charge $80 for the same field of work. Don't be scared to charge your original price if it's worth it. Remember, in business you pay for what you get for.

So finally, I would suggest you set it all up again if you are dedicated and your quality of work is still upto standards.
