Generally I could work up to 30 hours / week.
For one-time job payment is requested to be sent through Paypal on finished project. For longer jobs payments are to be paid after 2 weeks for the job done.
Preferred communication: my time-zone is European (Budapest, Berlin, Paris, Madrid), therefor during the day on weekdays I can take email or written messages. In the evening hours and at weekends I'm avalable to speak on the phone, Skype or Viber as well.
