Tried to find a post with an answer to my problem and no success.

I'm trying to remove the price next to this item, change the add to cart text to something else and remove the units: 0.01

What im trying to to is to have my customers pay their invoice on this site i created. I priced the Item for 1$ and I would like them to put the any amount and make a payment.
Everything on the product general option page is set to 0.

Help will be very much appreciated.
