you’re busy -- so let’s skip the small talk. 2 quick things: 1) I came across your site and LOVED how it looked! 2) I want to make you an offer that you can refuse, but I’m going to try my best to persuade you not to... My name is Evie Shephard, I help business owner and help deposit 2-5x more $$$s into my client’s checking accounts each month. But the way I do it is a little different than what you’re used to... Let me explain. I’ll help you rank on page 1 for google for $10 - either this helps you get more clients (and you make more money) or I’ll return $10 to you, give you an extra $100 (on top), and give you a FREE SEO audit (value: $297) Today I’m reaching out to a few people I’m confident I can generate BIG wins for and giving them the opportunity to snag up this limited time offer before it’s gone. I only take on 15 new clients a month, 13 spots are already booked, but you’re the first one on my list for the last spot. So can I light a fire under your sales and make you MORE $$$’s? I don’t need anything from you. I already know your target market. What makes them light up with desire. Tick. Wince in pain at 3AM. Everything. All I need is you go to , click continue for the “basic”, and my partner will set you up Then we’ll get to work to Deal? link : THANKS Evie
