Where can I get HIGH RES Viking logo picture?

Not sure if I am allowed to ask for this or not. But here is what I need badly.

I need the Minnesota Vikings face logo in a high res image. So that I can make it bigger and it will still look smooth.

Also I need the NFC logo inside a white cirle with a blue outline in a high res image. Or just the NFC logo with no background. Not sure what would look better on green grass.

Last thing would be the wording "VIKINGS" in a high res image that would look good in the green grass endzone.

I hope someone can help me with this, so that I can put together my field cover.

Thank you,
Tony
