Yes, there is a DIY store in Amphion les Bains [Cora Centre] where the shop not only has ready-made frames, but I think they will also give you a quotation for having your prints framed [at the Acceuil/Reception]. It's a little far from Geneva so you might try calling them first. Their name is Boite aux Outils. Good luck

Here you go!

I've had multiple pieces matted and framed as well as stretched and mounted. It has alwazs been a positive experience. 

many thanks misskate! but the key question is - is it affordable? CHF480 to frame a 1m x 1m piece is too much for me sadly. let me know, thanks a lot

chf480 sounds crazy! 

The largest I've had done is 70cm x 80cm and that was maybe chf100 for stretching and mounting. Framing with a mat and glass might be a little more, but I had five smaller pieces done at once and even that total was under chf300. 

He's a really nice guy, I've had very postive experiences there. I would say go ask, an estimate should be free. 

Good luck!

Why not making your own picture frame? Buy the various pieces of wood as skirting boards (length up to 250 cms) use a miter saw to fit all pieces into a 105X105cms square, use a three-ply cardboard carton (large TV screen type type), have a 100X100 cms piece of glass cut at the nearby glazier. Assemble and use glue for wood  and tiny steel nails plus a flat hook with a loop for hanging. You might also choose to paint wood if not desired shade. That should do.

A cheaper plan could be not to use wooden frame and only cardoard for the back, piece of non reflective glass for the front and adhesive tape for strapping all-arond of same color as dominant color on picture.
