We need a hard core magento developer who has perfect experiences on magento website optimization. Please see the latest website optimization report.
As per webpagetestr report, web content starts loading after java script loads which takes long time. you need to optimize java scripts and drag them to footer rather than header part.
Another issue is that insertion of each product takes long time to save.
A skilled magento developer should not take long time for it. If it goes well then you will have long time opportunity for work. Please reply asap with your skype contact.
