Produce webpage from excel data

General information for the website: To display sales figures.
Kind of development: New website from scratch
Num. of web pages/modules: 7
Description of requirements/features: I currently have a powerpoint presentation running on a PC which is connect to a LED Screen in reception. The presentation is populated by data held in a spreadsheet a network drive (in the same location where the spreadsheet runs from).

Currently, we need to get onto the PC which runs the powerpoint presentation and stop the presentation and hit a macro on the spreadsheet which updates the content on the powerpoint slide which is not really working.

I want a webpage to run on the PC which is connected to LED screen which pulls all the content from each of the tabs of the spreadsheet and then display each tab as a webpage using Internet Explorer in full screen mode. Once the webpage has displayed all tabs which are in the spreadsheet, I would like the process to start again. So it will go back to the first webpage which was displayed. In all, there is 7 tabs in the excel spreadsheet, each tab needs to be display as a webpage for 10 seconds before moving on to the next webpage/excel tab. The spreadsheet is not just data, there is also a coloured border and a jpeg as well.

I look forward to your suggestions on how best achieve the goals of this project.

Thanks
