Thank you everyone for your extremely helpful input and suggestions. Discovery Park has decided to go with AviSys as it was, hands down, the most frequent suggestion for flexibility and ease of use. eBird fans do not despair. AviSys 6.0 (the most current version) allows you to upload the data to eBird. So Discovery Park will be able to share records with the public in the future.
If anyone is interested in entering data feel free to contact me. Thanks again.
