Create Custom Spreadsheet Order Page in Excel and Google Spreadsheet

Make a custom spreadsheet order page for customers to simply enter quantities. Spreadsheet will have images we supply. And an example. You will go to our website and add all our products by category to the spreadsheet. There is also bulk pricing breaks so the sheet will need to update the final total of the order to the correct quantity price breaks. We will provide all the images for the products. There are about 90 products to add. I think it should take about 8 hours for this custom sheet. We would like it to look nice. Have some borders. Our logo. Instructions. Most complicated part will be to get the spreadsheet to correctly price the quantities to the price breaks. We want an Excel version as well as a Google Doc version supplied at the completion.
