"...because my goal is to blow you...."
I'd probably rephase this.
If you can change the order of your tabs, I would. Cake Flavors, Pricing, Portfolio (should this say "Cake Photos"? .... I never overestimate the intelligence of the buying public, and many will not know that portfolio means pictures) are the first things a potential client wants to see, but your first 3 tabs (after the home tab) are "all about me" pages. Move those to the end .... more of a "if you want to know more about me, read these AFTER you find out about my cakes!"
My personal preference is to actually list your email address. I hate being forced to fill out a form. I like being able to keep a copy of my email correspondence and forms don't let me do that. I understand why some don't want their email listed but my view is that if you're going to be in business, then you want it to be EASY for people to contact you. The method of contact should not be a double-secret-probation thing.
I've had a number of marketing people tell me to offer a guarantee and I've flat out told them "no way". I'm not selling shoes. I'm selling perishable product where the final "quaity" is arbitrary. SoI agree with everyone... lose the guarentee.
I know someone who told me they sought out foods in the grocery with guarantees. He wrote one shrimp company and LIED about how the batter fell off in the cooking and how it "ruined" their family reunion. Shrimp company sent him $80. This guy was running a small business collecting on food "guarantees".
