Original illustrations' prices vary whether they're spot illustrations or full page and the complexity/ color/ bw. (frankly, for illustrations it's a time-based fee. If you wanted me to hand-draw say, VanGogh's Stary Night on a postage stamp, it may cost as much or more than a full page illustration.
logos - $500
You give me your ideas, we'll discuss them, I'll design 3 drafts, you tell me if they're what you're looking for and we go from there. I'll design up to 20 drafts covered within the $500. Once you pick a final, you get 3 revisions on it.
If I make more than 20 drafts though, there will be an additional charge of $50/draft the flat fee. (this is to prevent me spending 6 months/year working with indbeyondecisive clients, on hundreds of drafts for one $500 job. it's happened.)
spot illustrations - $75
full page illustrations (8x5" x 11" or larger) - $250
Page layout is a per/page fee of $35. Unless it's a brochure or book or letterheads, in which case they'll be flat fees.
