You can use the Walmart send out service for medium format developing. They charge something like $0.84/roll for 120/220 C-41 processing, developing only. It's a couple of dollars more for some very mediocre proof prints. Don't be fooled by the proofs. Those 120 negatives of Portra are much higher resolution. I think they just scan them at a low resolution and then print.
For landscapes you may want to try something a bit more fun. Fuji Velvia 50 is very high in saturation and contrast. E-6 (slide) Processing is substantially more expensive I believe it is a bit under $5 a roll at Walmart. It really is something you should try out.
