I've recently built my own online (downloadable) sheet music store geared towards the child pianist who needs good recital pieces. The store is here:
Best Recital Sheet Music Store

I don't mind doing everything myself, but it would be really nice to work with another arranger/composer of kids' recital pieces to share in both the writing and the profits.

If you are a teacher who also arranges sheet music interested in selling your sheet music PDFs, please drop me a line at kimberly.steele@comcast.net.

I need someone who is working with Finale or Sibelius, has/can use photo editors like Photoshop, and who can make a PDF (Adobe Acrobat Pro) for obvious reasons. If you are chosen, you will also need a PayPal account to receive money. All the music in the store is either public domain or original compositions.
