As Vangogh mentioned about your index page.
Just an additional point to consider:
Search Engine Optimization should be one of your priorities. Your home page is very important for SEO success. When a site uses its Home (index) page as a splash page it wastes a valuable asset.
It is imprtant, especially for a designer, to make sure that his web site reflects his creative capabilites. However, a web site is a marketing piece, first and foremost. Isn't it true that you are developing yuor web site, NOT to show off what you can do, rather your hope is to **MAKE MONEY** ...?
Would you rather have a Web site that is the best looking site on the Web? or would you rather have a Web site that makes more money than any other on the Web? The answer, hopefully, is obvious.
My take is that if you are not even going to develop your own Web site to be the bst it can be, I'm certainly not going to let you develop a Web site, or any marketing piece for me. It tells me that you do not know what you are doing.
Granted, many Web designer/developers may use splash pages, but they are not marketers. What will get you a lot of business is if you stop thinking how to build your client a great looking Web site and start focusing on how to build them a great *money making* Web site and you will be successful...
There are a few createive reasons to use your index page as a flash page. Theer are about 5,000 reasons not to.
Sorry! Don't mean to bust your chops. Its just that it is that important...
