Did I mess up big time?

Dear NO!SPEC,

I checked out the NoSpec site and have a quick question on mockups and I would really appreciate it if you could give me some advice. Here’s the scenario. I just got off the phone with a potential client who’s looking for someone to design his logo. This happened a couple of hours before I checked your site. Oops.

He can’t draw so he just needs someone to draw a design based on a rough image he sent me and after he gets the sketch he’ll finish the rest himself on Photoshop. Now, he happened to mention that he’s getting designs and quotes from other illustrators and he’s going to check out everyone’s mockups and choose from there.

So now the question is, did I mess up big time? If so, what do you suggest I do about it? He’s also expressed some interest in buying some of my more expensive art later on, which if he does, will be much more expensive than this logo so I’d like to fix this without ruining the potential business relationship in the long term.

Please let me know what you think. I’d appreciate any advice you can offer.
