One honest piece of advice I would give to all newbies reading this is if you are happy with what you earn and your customers are happy to pay that price, then its a fair price regardless of anyone else.
However building rounds up take allot of time and effort and good marketing skills, and by time I mean years, not weeks, so if you want to jack everything in and go down that road, prepare for a long hall. But its a long hall that many have done before and got far enough down the road to say they have done ok, but many do give up as well.
So don't go into it thinking anything is easy because that can be the furthest from the truth, but again very much worth any hardship if you put the effort in.
