How to send a file back to employer?
I am a new freelancer. I have noticed that many employer want a freelancer to do some editing image first before hiring the freelancer. (The employer have attached the images of their product and tell the freelancer to do the sample job for them(especially photoshop editing). My question is after I have done their sample file, how should I send it to them?? (The employer )..And how would I know they don't just use me to do their job for free??
