Hi there, I read your brief and believe that I can complete this task for you. I can make it so that the excel information is portrayed on the page the way you have described.
The only thing is Wordpress plugins/widgets have to be created to do this, if not you would have to update the site daily.
As an example one widget would read the excel file which you upload to the server when modified and display profit and loss information, the other something else etc, multiple are used so you can display those pieces of information where ever you want, and it is not fixed.
This takes a bit of work hence the higher price.
I can also install a beautiful premium template for you so that you can do some nice customizations and page updates will be very easy.
Let me know if you are interested, Best Regards.
