Ask questions and learn from expert freelancers
I understand your problem. Especially with design-work, it's crucial that you understand what the client is saying, including the language-sensitive bits that might make or break your work because you didn't get a reference they were making.
In light of your problem I would advise to find local customers first to build up some kind of reputation (on freelancer.com too!) and then slowly start branching out in english. Ask a friend to help you out with translations if you don't understand :)
I think it's key to do an english course if possible, this will help you in any other job you have as well.

Its not necessary to be expert in english, you said your English is average which is enough. See main thing is that you understand client needs in project and just let your work speak for yourself. Good luck :)0 likes
