No e-mail address (or at least very difficult to find) - what do you have to hide? - Why do you not want anyone to contact you? I appreciate that publishing an e-mail address, leaves you open to possibility of spammers, but it just might bring you some customers!

No "about us" page. It helps to build confidence if there is a small section detailing names of who runs site, perhaps with a small biography and even a photo! Let your visitors know that they are dealing with a real live human being who has enough confidence in their site to be proud to put their personal details on it.

No contact details. As with above, at very least you should show a company name and mailing address, together with an email address and possibly a contact telephone number.

So to summarise:-

Tell your visitors clearly and quickly what your site is about, with a fast loading front page that has a clear benefit statement at or near top, answering question "What's in it for me?"

Have a means for your visitor to contact you easily - they may wish to buy from you!

Build visitors confidence by telling them who you are, where you are from and a little about your previous business experience.

I have to go now and check my site - ensure that YOU check YOURS!!
