Schedule plugin wordpress - repost

I have a whitelabel developer version of the [login to view URL] plugin (pleas google for there website) I can change whatever i want in the plugin. Becouse i use it for a school site i want a few changes in the plugin ADMIN side and Front-end. Also i want to delete some options in the admin side. Options that i want in (admin side) - admin must be able to change more than one event at once whit the options Sick, Day off, etc - Admin should be able to change one or more events from the back-end, but must select the event date, so not all events are changed. - Upload csv file with the events (is already in the plugin) but should work a bit better - Manual quick import would be nice, so you can add - edit 20 events on 1 page (name, time, date, sick-free, class, teacher) and save it. the following options should be changed/ deleted. - the option location should contain the classroom and a textfield for the locations of the school these options should be shown in the front-end. - The google maps function can be deleted. - event cost and tickets can be deleted - Organise and contact name should contain an option to select a wordpress user. the rest can be deleted. User should be visible in the front-end. - the plugin ask to have the location everyday this should be deleted. Front end - the event must show the following option (not yet click on the event) 1. title 2. class - teacher 3. start time - end time - ther is a option to connect ical and google agenda, works fine but the options that should be in the feed are the same just like 1,2 and 3 form above. The plugin is already there so the things i ask for is a change in the existing plugin, there is no need to write a whole new plugin. What i do want is the logo changed to one i have but i can do that myself.
