Seeking Distribution Channels for Carnegie Hall RFP on Data Management

Carnegie Hall Rose Archives is going to be releasing an RFP for a data management consultant next week and are looking for distribution channels that will hit qualified respondents, especially who are familiar with cultural heritage/arts/non profits. Any suggestions, recommendations, or individuals you'd recommend are appreciated here or directly to me via private message or email (rhudson@carnegiehall.org) - thank you!
