Hi. I just looked at the page in the link and I did not go much further into the site. I noticed a few issues with grammer. Have someone proof read your site. I have found many mistakes on my sites over the years.
"Our writers work hard and company have
all the skills necessary to provide quality services." This just does not sound right to me....
"Nevertheless, many students have not gifted
with appropriate skill of writing."
I suggest you open up a PO Box or add a physical address on the contact us page it will look more credible. Also list out your writer's qualifications. Do they have degrees? Provide a link to show samples of their work.
Add a nice human interest story on how and why you launched this site. I usually need background information on someone or their company before I purchase online. Here is the about us page from my main website:
I think a little background on who you are will make the difference in sales. Read the story at the bottom of my page this is the human interest story on why we started the business.
I hope my comments help.
