I would suggest you post some of your best images for C&C, and let us help you determine whether or not you are at a level where you should even consider starting a business. Most people on Facebook are clueless about photography, and that is not necessarily a good way to judge your potential.
We do teach here, if it is needed or wanted.
In general, if you are good enough to charge... then you should charge! If you are not.. then you shouldn't be charging (IMO)!
lol. i totally get where you're coming from, but man does this sound more than a bit pretentious. it seems like the majority of members on this site are hobbiests and low level semi-professionals. not exactly an expert jury on what customers want or are willing to pay for imo.
it seems to me what really matters is the opinion of the paying customer base. so ironically even though facebook may not a good measure how good a person is as a photographer, it may be actually be a better gauge as to how well someone will do as a business since it more closely relates to the opinions of your customer base (to some degree). i've see plenty of so-so photographers get plenty of paying customers through facebook or other
customer networking. none of that necessarily relates (or correlates) to the opinions of those more involved in the field.
