I know that I could write a very plain page, but I am wanting the site to attract investors (eventually) and all this stuff has to be done in my spare time.

I of course don't know what your definition of attractive is, but I do pretty well with just a text editor. The only problem for me is that I'm not a graphic design person at all. I suck at it. Still, I'm able to produce a site that (I hope) is visually appealing and, more importantly (IMO), functional. Here's two of my sites:
www.dignan17.com (should be XHTML compliant as well)
www.skerik.org

Again, I suck at graphic design, but I'm able to do just fine with only a text editor. For me I'm actually quicker with that type of program, and I feel you can create sites that look much better than you would with Frontpage.
