Web Developement, build a website - repost

I was looking for something to build a small website with a database in the backend. The website in my honest opinion isn't too complicated. This is mainly for a community. People would input their data in the form and these people would collectively form a chart. Say this is a global website and all IT engineers input their data in the website, showing how much salary one gets in what country. The salary would then be divided in hourly, daily and monthly. Main currency being dollar. One can access this chart after signing up on the website. The domain name, space will be provided by myself.
