Advice on Affiliate Site

[JudderMan]

Hi guys, a few questions if you don't mind:

Have you used CarTrawler? If so, any opinions on it?

Do you set up a site first and add the booking portal a few months later or can I sign up and build the site around the booking portal on the go?

I prefer WordPress and know it well, but I think the themes look terrible and prefer Joomla, but it seems to take 3 times as long to do anything, opinions on an aff site through WP or Joomla? Also, I need a good theme for Joomla, I've checked tens of sites with free ones and they are all pretty lame...any ideas? Or how much to get one made?

I have 80% of the content for the new site, is it really bad to bomb the site with a few hundred articles in the same day? I don't want to have to wait a year to eventually put all of the content on.

Is there a quick way to load content into a site? ie. bulk loader or something, then I can chip away at on-page SEO. I don't want to employ anyone to do this as it's unique content and it would be damaging to my business if it was used by someone else - I prefer automated methods anyway.

Erm, I think that's it for now. Thanks in advance if you can answer 1 or all questions.
