Required software development,Website Development freelancer for Other site page parsing at client bowser job

I need to show a number from 3 different sites at my site, but I don't want to save this data at my site etc, I want to this parsing works not at my site, but at browsers of each of my site readers (JS?). Script must not show or style or represent data anyhow, just get-parse data from other site and send needed number to another WP plugin at my site. I need this parsing from 3 sites and I will tell which classes contain needed data so parsing will be very easy for you. Code must have dynamic incoming values: parsing site (A/B) and exactly URL of page which must be parsed. It must work as a WP plugin.
You must have a good portfolio with plugins, 2days.
