I did not manage to find the email aor/and contacts of the author of this skin to ask if he would allow to use his work or if he himself/herself is planning to do a Window Blinds theme.
This would be crucial for someone wanting to upload/share the work. If you do it for yourself with no plans to provide the content to others then there's no problem.
What might work best is to get help from some of the master skinners here so you can "finish it" yourself. You can also try skinartistry.com as they have a great workshop for new skinners.
