Last name? Why do you not have a business phone? What if I have an emergency problem that needs to be resolved quickly and the email I've sent isn't read till the next day?
Also, why don't you have a logo?
1. Last Name: Kukla (As found in my email)
2. I get my emails on my phone, if I'm awake I'm "on call" via email.
3. We don't have a logo because we don't find it necessary, although, we do have our company name in some nice fancy text.
