My girlfriend want to move to sweden from accra. How do I start?
A travelagency in accra whants:

Passport 350usd
Vacc ard 45usd
Visa 500usd
Medical report200usd
Insurance 200usd

That seems crazy..

What's is right?

It is crazy.. because you are being scammed. Sorry.
It's a very popular scam:
Romance Scams | Embassy of the United States Accra, Ghana
About Romance Scams

Like NK states... you are being scammed... can't you find a real girlfriend you will ever actually see where you live? I bet you have never actually seen this "Girlfriend" in person, then how could she be a real girlfriend if you haven't. Women actually slightly outnumber men in most parts of the world. And they don't all live in Accra, Ghana which is a third world hell hole that's got plenty of men. Most of which apparently have rich uncles in Nigeria that email people worldwide looking for suckers to give them money so they can get some imaginary inheritance released.

Do not send her any money....as the others have said, you are being scammed and this is not real. IF you send the money, you will not see her and you will lose that money.

First she is not a girlfriend. In fact, it may not even be a "she" there are large business that do these scams on people all the time.

First the passport is not near that much money. And I am laughing at the visa cost, but that is still less than they ask often. Normally they start at about 3000 USD for passport and visa

And why USD, if she is going to Sweden, she will be paying in her money for everything but visa, and visa would be in the money of Sweden.
