At what point do you as a startup justify spending a huge amount of money on a "designer" to tweak a font? Does it look nice? Absolutely.
Would I, as a business owner, pay a lot of money to change one cursive font to a slightly different cursive font? I'm not so sure.
Sub question: What does a design tweak like this cost? From what I've seen, sought after designers can go for some serious $$$.
