Traditional, as far as I know, requires nothing. Arrangements are the individuals way of expressing the tune/song. I've done a couple of things with trad tunes and have had no problems - and they are free. I certainly understand the "pay for" thing. I lost my butt on my deal! Vowed to never do it again!!

When you are done post it on the forum as lots of musicians here swap CDs (me for one) and others buy them.
