Dear Employer.
I’m reaching out to you because I’m a freelance experienced in a AutoCAD, Photoshop, Word, Excel, PowerPoint, PDF, OCR, Web Search, Data Mining, Scraping, eBook, Data Entry etc. looking to build my portfolio in the above type of area of assignments.
Because I want to build my reputation in this area, I’d be willing to do "Alter Some Images" for you without charge. All I’d ask in return is your willingness to refer and recommend me in future if you’re happy with my work – and not to mention that I did this project for you without charge. I also need to be able to claim credit for this piece.
We both win here – you get free help and I get a valuable portfolio piece to my credit. I’m happy to tell you more about my [your type of freelance niche here - writing, design, etc.] background and discuss this with you further.
Let me know if you’re interested –
