Our website at [login to view URL] loads pages very slowly as you'd observe when you visit the website. The site is being hosted on a virtual private server. Can you make it to load faster? To prove to me that you can make it load faster, bid bhy answering the three questions below: 1. What could be causing the site to load very slowly if the hosting is not an issue? 2. What do you suggest as the best way to make the site to start loading very fast? 3. How quickly can you implement your suggestions in 2 above to help the site to begin to load faster? PLEASE NOTE: The script for the site is encrypted, and not human readable, in case you are thinking you could adjust anything on the script. The person who provides the best answer to the above three questions will get this project. Thanks for bidding
