Help With A Word Order Database

I am a modular housing sales consultant and I am trying to setup a work order database in access. This database would allow me to spec out a modular home for a prospective customer/client as they provide me with all of their home options (floors, exterior, doors & windows, interior, appliances, bathrooms, kitchen, etc.) and then print out an invoice with an estimated total.

I am currently using an excel spreadsheet and it is very cumbersome to use. I use it as an invoice and the invoice contains the following information on it.

Bill to:
Dealer Name
Dealer Rep
Phone, Fax, Cell

Ship to:
Customer Name
Customer Address
Phone, Fax, Cell

Home Options:
Floors:
Joist: (Structure Wood 2X8 Joist, Structure Wood 2X10 Joist, Plywood 2X10 Joist)
Carpet: (Cappuchinno, Biscuit, Pebble, Summer Straw, Praline, Herringbone, Cashew, Buckskin, Shale, Botanical, Cordovan, Stone, Cascade, Black Ice)
Vinyl Flooring: (Woodgrain #05296, Square Tile #57296, Mosaic #55296, Tan Stone #08296, Large Square Tile #07296)

Interior:
Interior Doors: (install, ship loose, 6 panel, flat)
Hardware: (Brass, Brushed Nickle, Round Knob, Level Handle)
Crown Molding: (4", 5")
Base Molding: (4", 5")

Appliances:
Color: (White, Black, Bisque, Stainless)
Dishwasher: (Standard, Power Scrub)
Microwave: (Over Range, Free Standing)

There are other options but this is just a brief listing of options as an example.

Each option would have a price attached, and selected price would be added to the invoice, and once work order is completed, the invoice would have options totalled. Ready for the customer and dealer to confirm and approve.

Can someone start me in the right direction on getting the tables setup for this - the one that I seem to be having the most difficulty with is how to setup the options for this invoice. I pretty well have a grasp on the others. I might also need help in relating the tables to one another.

I hope this all makes sense.

Any help would be greatly appreciated.
