I've got a site - tritonavdesign.com, for a division of my company which sells and installs outdoor/pool entertainment system equipment. (Sound, outdoor TVs, outdoor intercom, security cameras, outdoor lighting control, networking, etc.)
I would like to have a "Packages" page on my site where my customers can go online through a streamlined process to set up their own estimated quotes to choose what they would like to have for their outdoor system, whether it be speakers (of different variants), security cameras, lighting control options, etc.
For example, they could go on the page, and begin the process by clicking on a button that says something like "Begin quote." They would be then brought to a page where they can select how many speakers they want (and what kind - ranging from good, better, best) and a general subtotal would be made. They could then go on to the next step, lighting control, etc.
This is only for estimates/quotes, so no ecommerce capabilities/payment gateways are needed. I have seen things like Gravity Forms and WooCommerce Quotes and Orders do similar things but I'm not sure it will be exactly the same.
Anyone know of anything that might help?
