Webpage Takes Many Seconds To Load, I Want To Reduce It To 3 Or 4 Seconds Max

My website takes several minutes to load. I need a skilled person who can start work immediate and finish within today  .  URL of the website will be given to the skilled coder.

Looking forward to increase scores on all the below testing tools

1.  Google page insights
2.  Pingdom
3.  GTmetrix

The score should remain consistent and should not drop after some time. Payment will be released after closely monitoring the website score for a week . only for serious bidders who know what they are doing. No time wasters please !!!
