if someone came on here asking the following question, what would your answer be?
"I'd like some photography for my business. The problem is, I'm not a professional photographer, and I haven't got a firm idea for a starting point. I'm considering clipart, available from a number of sources. Has anyone tried using clipart for photography? Did it give you a good result?

"
my guess is you would say:
"hire a professional photographer who knows what he is doing, because clipart is NOT the same thing at all, and you're going to look unprofessional if you try to do that, or try to take the photos yourself with primitive point and shoot gear and no photography skills."
similarly, my advice for you (as a design professional, who has done extensive international work for sony, mcdonald's, international trucks, and many more large companies) is to hire a professional designer or art director who has an established track record, and a portfolio full of other logo work that you like and respect. pay him what you need to pay him, because logo creator software is a joke, and if you're serious, you need the services of a real design professional. the trick is to get someone good who you trust (look at the work CRITICALLY just as you would another photographer), becuase they are NOT all created equal. just like in photography, there are probably 20 hacks to every quality professional. but yeah, unless you want to look unprofessional, hire someone who knows what they're doing, because trust me - it makes a big difference.
