Good goal!
I'd put together just ONE killer product,then I'd build ONE Killer squeeze page, with all the time, money, and thought going into that sales copy, and then send all my traffic driving efforts to it.
- guest posts
- article marketing
- forum posting
- blog commenting
etc..
I'd give this killer product away, and market to the list.
Since you're going for something simple, you could invest in it making sure you were giving away something that other people were charging money for!
I went the other way, built a blog with hundreds of posts, a list, a twitter following, facebook following, products, etc, etc...
This is how I'd do it if I lost everything tomorrow!
Think about it, my marketing efforts are spread out. (I have 4 products, and 12 websites)
There is no way I could market to all my sites for the same amount of time/effort/money you could to just one simple (yet killer) squeeze page.
