Your safer crating a separate page for the promotion and not doing it on your personal profile, you can then log in under the page name so any group post or comment you make link back to the page.

There's quite a bit of selling on Facebook, they do crack down on some affiliate links to money making schemes, etc. in the Facebook spirit you should emphasize the cause and have the but like more of an afterthought. Using Facebook paid ads to attract people to like the page is one way to get attention, if you get 30? likes you can edit the address they give, cutting out the digits at the end.
