I'm actually an efax member. But, for some reason, they don't offer this specific service.
Maybe I should clarify my problem a little more:
I manage an online directory where people use the site to contact individual vendors in the directory. Some of the vendors do not have email, so when a customer fills out an inquiry form, it gets emailed to me and then I have to manually fax it to the vendor. (which is starting to get very time consuming)
I basically need the form results sent dynamically to the fax number for each corresponding vendor when the site user clicks "send".
