Artist Needed for Logo Design

I have big plans for the coming months. The details are still emerging, but these plans will involve my return to a more active role in the local community as well as a renewed effort to advance my career as an author, teacher, and public speaker. In light of these plans, I'm looking for an artist who can design a new personal logo for use on my website and any printed materials I produce.

Earlier this year, I discussed my new logo plans online in public and private conversations with a few dozen friends. I originally was planning on using a popular tree image that I found online as a template for this logo. However, it turns out that this tree image is copyrighted and unavailable for use. Therefore, I've decided to seek out an artist to design a new logo from scratch.

This logo -- or sigil as I prefer to call it -- will be used in a variety of personal and professional contexts. It will appear on my website, business cards, letterhead, and any books or other materials that I self-publish. I may even put it on my clothing eventually. In essence, it will become the artistic equivalent of my signature, much like a family crest or seal.

Unfortunately, I don't have the money right now to pay an artist for their services. However, if I do use the logo you've created, you can add it to your portfolio of professional work, and I will give you credit on my website and in my books.

I already have a fairly clear understanding of the basic elements I'd like included in this logo:

(1) A circular border, preferably in the style of Celtic knotwork.
(2) The silhouette of a tree, specifically an oak.
(3) A treble clef in the trunk of the tree at the center of the image.

The image should be high resolution and scalable, looking good at both 2" on a business card and 10" on a sign or T-shirt. It should be in either black-and-transparent or black-and-white.

If you're interested in submitting such a logo for my consideration, please let me know either online or offline. Since I currently don't have the money to pay what such a logo would normally cost, I'm going to have to rely on the kindness of any artists who are reading this message. If you're a new artist with little or no professional experience, then hopefully the extra exposure for your work will help you out too.

Thanks in advance for any submissions or other feedback. If and when I find the logo I'm looking for, I'll be sure to let everyone know.
