Ummm... I don´t see all options available on your poll.
I´d personally go with a company that:
- Has an amazing portfolio with consistent quality standards;
- Has much bigger otput capacity than a single person;
- Has good copywriting skills;
- Has History in the Biz;
- Works hard to provide their clients with unique design and branding solutions that deliver HIGH ROI, with a professional and friendly customer service.
