Where to Print real big enlargments

If any one out there can be of assistants I would really appreciate it.
I have an order for 2 prints for a wall
2.7 meter's high
4.5 meter's wide
Is there anywhere I can get this printed in one piece.
The height can be 2.5 meter's but preferably 2.7.
I need a very high quality print as the distance from print to person watching is minimum 1.5 meter's .
I can print near me on a LAMBDA 1.27meter's by as long as I like so
I can do each shot in 2 pieces (trying to avoid this).
Any suggestions
Thank You

Hi, Just received some very large prints back from mpix.com as well as some medium size and are totally delighted with the quality and the packaging is outstanding especially as I am in Canada. I have used them before although not for so large and I needed to get them done where I trusted. Recommended.

MPIX can't handle this size print. They max out at 24" on their website pricing. I've worked with myphotopipe.com and they max out at 60", but I like their large work. I've just had 2 30"X40" prints and a 24"X30" done there and will be following up with a couple more when I have time to prep them.

2.7m is 106in width. Duggal in NYC is a company I've seen referenced in the past for extremely large 1 piece photographic prints, but I've never worked with them myself.

You might want to look at sign shops Avi, as they'll be used to making things like large banners. I'm not sure how many of them could also print photos, but it might be a start.

Thank you to all for your suggestions Because of logistics the photo will be done in 2 pieces and put together at the place .I am using a LAMBDA printer and having them stick it on PVC for me .
Thanks again
