Will you provide any custom modifications to your extension for an additional price above the main cost of the subscriptions? I am currently using a different calendar system, and I am looking to get a new calendar system and have a few things added to it. I don't have the full list of modifications right now, but a few would be the ability to have an image display on the Calendar view for each event, additional payments other than PayPal (directly on the site rather than going to an external site), and ability to install multiple calendars and have separate login accounts for each calendar. If this is something you would provide for a fee, please let me know.
