Some great packages you have there maybe try brush up on the following pointers.
-1800 Bandwich-you mean 1800Mb Bandwith (1.8Gb)
-Why use a @gmail.com for selling hosting?
-You dont tell us about other features like sql mails
-You dont tell us the control panel if there is one.
-You dont tell us how to pay and what payment methods you accpept.
-What kinda servers do u have.
Other pointers include
-A ip address
-Support customers will get if they get any
Sorry to say but this is a outrage and this topic should be locked.
Id just like to add i wouldnt go anywhere near you before you brush up on the above pointers
