Having some online work could help to start with, you can set one up at carbonmade without knowing a lick of webskills. I don't know if I'd take a trip over to show my book around (although this does help, personal interview and all) unless I had a friends to crash at, since you'll likely not score a job on the first tour but probably a few good leads.

excuse my portuguese.

Thank you so much! All these agencies look great!
So much creative sparks! LOve it!

What you find to be the best for me to do. Contact the agency by email, or just go there with my book. Dont have any contacts, so iam kinda hummm! Can i share my book with you, if you find it cool and want to pass it on or help me with some contacts, would be great!
:)

Stockholm is great for me cause i can fly very cheap to Porto.

You are really something!
thank you so much!

By Sweden, I'll assume that you mean Stockholm where the multinational and more famous creative agencies are - though there is Forsman och Bodenfors in Gothenburg that has done consistently good work for over ten years and The Fan Club in Malmö have a lot of fun too.

I'd have a look at
King (also London - two birds one stone)
Åkestam och Holst
for the non multinational agencies.

(commercials from Åkestam and commercials from King and here are some ads from Forsman in the archive)

Check out Goss too.
Not sure which multioationals you'd fancy but they are easy to find. Someone else might reccomend better agencies in Barcelona and London than I.
