Best plugin for Budget option

Hi everyone,

I’d look and tried a lot of plugins in the last days.. What I’m looking for is like an eshop plugin, but much more simpler..

Instead of a plugin to sell productz, I need a plugin to budget my products. Like a contact form in the end of every product post, with the costumer filling the details, the plugin has to grap the product ID and maybe send an email to the costumer and to the admin.

Do you know something like this?

??
