Need a price quote engine Folks, I need a module that will give me the ability to collect service requests from anonymous users and will return to them an estimated price, so a quoting engine basically.  I need the information they submit to also be summarized and sent in an email to a sales rep.

I know about Ubercart, but it seems to be overkill for what we need.  Does anyone have experience with it and can vouch for it as far as this problem goes?

EDIT: Further elaboration on collecting service requests.  The requestee selects a few services that they require, and in what quantity, and this request is forwarded to a sales rep who then prices out the request and contacts the requestee via email with a price quote.  Really I see this as a one way mechanism where requests are just submitted, and then the rest of the conversation is carried out either over the phone or via email.
Receiving requests

With webform, you can create forms that allow you, or your site-admins, to create and maintain the form that site-visitors will fill out. When the form gets submitted, you can use Rules to send this information on as an e-mail. The module Webform Rules, provides the bridge between the two modules, allowing Rules to react to webform events.

Answering requests

Just turn the whole process around. Again, use webform to create a form for the request reciever to fill out. When this form gets submitted, send a mail to the requestee with the reply.

Custom work

You will most likely need to do some amount of custom coding to make this whole thing work. For example, in the mail to the sales rep, a link must be autogenerated to a form that gets prefilled with the requestee's e-mail. Auto-filling the form is likely best done as a hook_form_alter. There is a lenghty Rules video series that you can view to learn more about how to work with Rules and how to extend it to do what you need.
