Reviews on your site mean nothing for people in this forum, as people always want to buy-sell using escrow to secure the funds.
Why people want to buy ASICs on your site instead of buy it directly through bitmain? Build trust is the most important thing if you want people trust and buy products on your site.
Another thing about your location;
AsicWorld
Dezheng Road,
Shilong Shiyan Town,
Bao’an District,
Shenzhen City,
Guangdong
518108,
China

If people have to purchase ASICs and shipped from China, it's better to order  on bitmain site obviously.

why don't you accept paypal?

i'm happy to buy all the s9's you have in stock and will pay for the fees paypal charge.

Do asics mine well on the bitcoin cash network? Considering purchasing one since I am an avid gambler in need of money.

If this is not possible, then I don't know how to quickly build up trust in the community. Its normal to not do that but to say it emphatically might send the wrong signal. On the forum here, there is a way trades are done to make everyone happy and selling of an hardware with such high fees then there is nothing wrong in making compromises in other to get accepted.

The main important thing is, who will trust you first to go with over $1000 without any form of control or escrow to protect his funds then come back to the forum to give a review but going through the forum way of doing things might make that come faster than you thought. My opinion though.
