How to show the progress of a PRE-ICO on a website?

How to show the progress of a PRE-ICO on a website, and block the purchase of additional tokens once the limit indicated for each round has been reached?

Build a tool for this to track amount of sales

@MrTurtle Any step by step guide to build a tool for it?

No, for most items according to ICO’s there are no how to do tutorials for 2 reasons according to me:
When holding ICO you should have the capacity’s in home to build it on your own/with team
Every ico has other requirements

Step 1. Hire smart programmers

All other steps after that
