How can I remove the price from my order form

Our price varies depending on the model so we would like to remove it.

Ecocruise Pre-order form...

If I set it to 0 or remove the price it changes it to FREE. I would like there to be no price and have them call.

I have it set to a .01 right now but I would prefer not to have anything.

Thank you

You may set the price to $0 and inject this code:  

.form-product-details{

    display: none;

}

I hope this helps.
