I'd look in the yellow pages for a graphic design company, if you find the online services insufficient and are not interested in learning to use a photo editing program (free or paid) yourself.

I need a Graphic designer who knows both of Adobe Photoshop and Adobe Lightroom. My question is where I can get a professional Graphic designer or is it good to use online based software by which I can get clipping path, photo retouching, shadowing services?
Please reply me.
