I have to see if I can part with the funds now or later

The first link does the actual bare-bones ordination for free, far as I can tell. You'd only pay if you wanted to order (I'm not kidding) "Ministry in a Box" or some other such helpful aides.

These sites are great! They even provide you with letters of good standing in the Church if you need them! (Some states require proof that you're "a member in good standing" before you can perform all your duties.)
