Couldn't get more than one order in past 3 months

[ajfreelancer]

Hi,
I am working very hard day and night to get orders on fiverr, I have made 5 gigs improved their ranking in search engine regularly as much as i can according to my knowledge. In these days i am trying to grow my portfolio and improve gig description and images, sending 10 buyer requests regularly but seems no luck. Please guide me what should i do more.
Really appreciate for any help.
