I will make you an original instrumental theme song/jingle for $5. You will be able to do whatever you want with it because it will be completely royalty-free. I only ask that you please do not resell it directly, but selling something with my work used (ex. video with purchased theme in it) is fine and royalty-free. Specify a genre and you will get a theme song. I can send it in various formats, and even offer the original sheet music as an add-on. Custom duration, limit of 45 seconds. I do offer unlimited revisions; typically I will send several drafts and get feedback from the customer and improve it. I do not stop this process until I reach a piece the customer is happy with.
