Crappy Banners - why don't I know any graphic artists?

Tonight (okay, today) I changed my shop name to "Worthen's Mercentile", so very exciting.  I'm so glad that Etsy has made some changes so that folks can see my name and my shop's moniker instead of my childhood nicname that I first signed up with about 3 years ago.  I also struggled with the paint program on my dying PC to make some sort of Banner.  It took me about an hour and it sucks.  I don't know why it is so hard for me, but I also just can't figure out why and how I don't know someone who could whip one of these up for me!!
