Okay well, if you are going to have that many courses your meals must be on the smaller side and not too heavy. You don't want to have huge portions of chicken parm. and then expect people to eat three more courses after that.
You can always start with a small salad, but dress it up with some fruit or nuts. Depending on the type of affair it is you could have a cold vegetable appetizer: take cucumbers and hollow out the middle, fill it with seasoned cream cheese or hummus and then top it of with a split cherry tomato and shredded carrots. (What you want to go for is not to fill the peoples stomach up within the first two courses but rather make the dishes have a lot of flavor. So you need to be good at seasoning.)
You can have shrimp wrapped in pancetta for the next appetizer. Once again not too much, only a few shrimp. One of my favorites is grilled vegetables. You slice thick pieces of zucchini and grill it. Then grill very lightly thick peices of tomato. Get some fresh mozzarella and add a little salt and pepper to it. Next what you want to do is take a slice of zucchini then tomato, them fresh mozzarella, then another piece of tomato, and zucchini and make it into a stack. Top it off with a piece of roasted red pepper and basil leaf. You can add a few more herbs depending on what you like and drizzle it with olive oil. With this dish you can adjust the size depending on if you get a big/small zucchini or if you use beefsteak or plum tomatoes.
After this course you could have a pasta dish but keep in mind that pasta is very filling so if you do have it, don't have it with a heavy cream sauce or anything like that, keep it light. You could even add some type of fish to this, either crumbled salmon or a shell fish like lobster/crab/mussels/ clams or craw fish and scallops. Worse comes to worse, if you don't want to have a pasta dish you could always have some type of water based broth soup, but thats up to you.
You said that you wanted chicken cordon'blue so you could have that at this time, I wouldn't start off with it, if you want your guests to be able to eat the rest of the food. It has cheese and meat and chicken, which is heavy and should be the main meal. Just make sure there is room for dessert.
If you want a killer dessert you should make lava cakes. They are small and personal but very thick and heavy. (There is a reason why they're mini cakes) If you haven't heard of them before, they are small chocolate cakes and when you cut them open in the middle, it has a gooey chocolatey center that oozes out, EXTREMELY TASTEY!!! They are pretty easy to make and you can get their recipe anywhere. Try www.foodnetwork.com
I like to add a piece of a pizzelle cookie with some whipped cream, fresh berries and powdered sugar on top. The light airy cookie adds some crunch and the berries a little tartness and the whipped cream is just so good and perfect with this dessert.
The last thing I am going to tell you is that your food must taste great and look great. Presentation is a lot. As long as you drizzle some type of sauce on top or around the dish, or sprinkle powdered sugar over it or herbs around it or have the meat or vegetable stacked up, it will look like the head chef at some very fancy restaurant created it!
Sorry this is so long, but food is my passion. I hope you like my ideas and have a great time making the food!
