Hi Regina,
I spent quite a while looking for photographers in the area as well, including Sofia. It's so hard to make these decisions from abroad! Did you see Octavio Montes? I stumbled upon his reviews on this website and he was highly rated and he had what I found was better pricing than most other photographers in the area. My wedding isn't until Jan 2017 but he has been very responsive and easy to work with so far with working on what time frame I want, certain looks and shots I'm looking for etc... We are also using his videoography service which also appears to be better priced than others in the area. If you want a good price photographer check out http://www.octaviomontes.com/.
