i have looked into having designers worldwide, working remotely. i had planned on using Skype as a means of contact (and to keep costs down), and my website could then be used to present to clients, uploaded by any designer anywhere.
i have posted on a design forum to find possible designers, of which i had loads of replies.
will need much more research though, but could be fantastic if it works.
i cant see there being too many pitfalls with virtual working abroad, but obviously knowing the standard & quality of work you will be getting is essential.
what were you thinking of?
