If you wish to consider framing the print yourself, Frame Destination a frame manufacturing company that I use maybe of interest. They offer a variety of frames and mats for you to choose from and on-line viewing of what your framed print will look like.
Some things that you will need to consider as you frame you image will include do you want a metal or wood frame (my bias is metal), what type of mat board, how much of an art overlap do you want, what type of glazing and backing. The following information and web-links may be of use.

Types of Mat Boards
I recommend that you start with a 4-ply single archival mat board that is made with either cotton rag or alpha cellulose. If you have a desire to mat your print as you might see in a museum, then use an 8-ply single archival mat.

Art overlap, which indicates how much of the image is covered by the mat board, is typically 1/8 to 1/4 inch. If you want to leave a boarder around the image you can select a negative number and the mat window will be larger than the print.
Your selection of frame glazing materials, glass or acrylic, is critical to preserving and protecting framed artwork, photos, and prints.

Quality frame backing board protects your art and makes it easier to mount prints and photos. Backing board, also called mount board or foam board, supports and protects your artwork within the frame. Please consider buying acid- free.
