Where can I find the Rubank collection of clarinet solos online to pay for a download?

Tomorrow I will be performing “Nocturne” by Luigi Bassi for a church offering. However, I do not have the piano accompaniment part. Now, I’m not necessarily looking for a free version, but I need something that I can get right away. I can’t wait for shipping or anything like that. So, if you know of any downloads or Ebooks of the Rubank collection of clarinet solos, which has the piano accompaniment to “Nocturne,” please let me know. That would be much appreciated. Thanks!
