Hi Duane,
Internet marketing works on a practice what you preach modual (at least that's how us old skool folks look at it and work it) and that's what you have to convince your leads and potential customers of, that you DO indeed make money from home. Scrap the blogger host - there are lots of hosts out there for a reasonable price (host gator being one of them), hook up some autoresponders for lead generation (aweber is cheap, $1 for the first month) - follow the 3 to 5 mail out practice. And NEVER, ever dismiss article writing, that is one your key sources for getting your name out there and getting those much needed back links from directories. Everything you've mentioned is pretty much oversaturated, but you have to look at it from a different angle, it might be oversaturated but there's crap and then there's quality and believe me when I tell you, there's a lot more crap, than there is quality and that's your mission and objective, providing quality over crap. People know and see the difference.
