My longtime neighbor and friend since we were toddlers is a photographer and has been begging to do my wedding photography for years. She has never mentioned whether or not she would charge me for services or not or discount them..never really discussed that but because I am having a destination wedding in the Dominican Republic I was planning on asking her to do my photos with the exchange of me covering her travel and room costs. Is this reasonable? Or do I ask her to be my photographer and wait to see what she says about pricing? Obviously she is a friend so she is a guest regardless. I just don't want to look cheap and I also want to respect her as a professional!
