    Ok, I think I understand your question now.

    You want to draw text a curved path…

    Good news/Bad news:

    Canvas cannot do this directly.

    However you can use Html SVG to do it.

    You can use a free program like Inkscape to design your logo.

    Then just save it in SVG format (myLogo.svg).

    Then you can load it into canvas like this:

    var canvas=document.getElementById("canvas");
var ctx=canvas.getContext("2d");
var img=new Image();
img.onload=function(){
    ctx.drawImage(img,0,0);
}
img.src="http://mySite.com/myLogo.svg";

    Here is a quick demo of the kind of SVG you can create to fit your needs.

    And here is a Fiddle: http://jsfiddle.net/m1erickson/v4EX3/

    <!doctype html>
<html>
<head>
    <style>
        body{ background-color: ivory; }
        div{float:left;}
    </style>
</head>

<body>
<div>
<svg viewBox = "0 0 200 120">
     <defs>
         <path id = "curvedPath" d = "M 10,90 Q 100,15 200,70 Q 340,140 400,30"/>
     </defs>
     <g fill = "white">
         <use x = "0" y = "0" xlink:href = "#curvedPath" stroke = "black" stroke-width="40" fill = "none"/>
         <text font-size = "20">
             <textPath xlink:href = "#curvedPath">
                Use SVG to put your text on a curved path like this!
            </textPath>
         </text>
     </g>
 </svg>
</div>
</body>
</html>
