Setting up scheduling events page

I am trying to set up a section that would allow people who visit my website to schedule a seminar with me. I have played around with it some and looked at the help info on the subject, but not getting the answers I need.

I would like people to be able to pick a seminar they would like for me to present (there are several options) and also allow them to pick a 3-day or 4-day period of when they would like to have the event (3-day events would be Thursday, Friday, and Saturday; 4-day event would include Sunday). I would also like to make sure there is plenty of notice, about a month in advance so I can confirm the dates are available (not necessarily for scheduling conflicts regarding seminars, but that I will be able to personally make those dates).

If anyone can help me with this, I would greatly appreciate it.  Thanks.
