I am a new freelancer, and your project is all I am looking for, and trust me I am the person you are looking for! As I have a very adaptive mind, I learn from tiniest changes to fine tune my responses, also I don't claim that I cannot make mistakes, but I sure as hell keep the guts to accept if I do make one.
As for the required skills, you text me for any sample work, and if you like it then only hire me at a rate which fits your budget.
Lastly, a good news: I can start Right Away!
EDIT: As for the pricing, I charge about Rs. 100 (2AUD) per Image for heavy editing, so I can do the work in 80AUD for 40 Images (including Freelancer's Fees)
