Google apps script to login to my website and return html text back into google sheet

I need a google apps script expert to write a script that accepts a username and password input into 2 google sheet cells, autologins to my website user profile area and returns specific html text back into the original google sheet. I have a working script for another website which could be used and adapted or you can start from scratch with your own. Looking for someone that can start immediately and finish asap. thanks
