Dear Sir / Madame,
I have a lot of experience using Adobe Photoshop, I use it daily and am an expert with the software.
My skills range from graphic design, to photo editing and digital painting.
Looking at your requirements, I believe myself perfectly suited to the task.
My work is usually for TV brands, and the BBC in the UK for example, who all demand very high quality.
If you gave me a small example / task to complete, I'd gladly do it to show you the quality of my work.
I hope to hear from you regarding this project.
Kind Regards
Matthew
