Umm, FattyMcJ, do you realize the OP is in Abu Dubai? I have no idea if that place is crawling with starving photographers, or whether the OP has the field exclusively to himself. I would think that Samerr, given his relatively recent experience, is being cautious to not overpromise.
Thank you also for posting those two links. The phrase "leaving money on the table" is one that leaves me with some distaste, as it is a phrase that some salesmen in my industry (I own a contracting business) use as justification for charging outrageous fees. The reason that particular phrase is repugnant to me is that it implies that the customer is prepared to pay a specific amount, and if the salesman isn't able to get that full amount, then they "left the money on the table". Of course, reality is much more complicted, and the amount a customer is willing to pay may be quite variable - they may agree to a much higher amount, willingly, if they understand the value equation, and if that value is important to them. If they don't see the value, then they will balk at paying "outrageous" amounts. My customers usually end up paying 20-100% more than the competition, but that's because I focus on delivering an experience and end-result that my competition just can't match. Other than that particular phrase, I am in general agreement with John Harrington (the writer of the items you linked to), that any business person (photograher, contractor, caterer or other service provider) must create in the minds of his/her customers an appreciation and desire for the service being provided.
Returning to the OP's situation, I think that his work has excellent promise, and once the skill level (and confidence) is there he will be able to convince his prospective clients of his value.
