Site flipping help needed - Social Bookmarking vs. Article Directories / and more

After a lot of reading and learning, i decided that i want to start my IM career by site flipping.

I know that ideally one should do both, bookmark the articles on his own page and submit articles. But since i dont have alot of time and am quite unexperienced, i think that writing a single quality article would probably take an hour. Together with the other stuff, bookmarking, posting on popular niche boards and so on, i guess i would need 2 hours a day for the business.

I came to the conclusion that social bookmarking is far superior for my purpose, because it gives guaranteed traffic. Also, by using socialmarker.com i can build a guaranteed 50 backlinks per day to my article what would please Google. Also, i plan to choose a broad topic for the page, and dont focus on specific long-tail-keywords. I hope to please the audience, instead of focussing solely on search engine traffic.

I dont know yet what system to use, i have no experience with Wordpress and its kind of hard to transfer. I have a little experience with Joomla, but i think its overkill for a 100 article blog and i dont know how hard a transfer would be.

Any advice or suggestions?
