If it was me starting over again,
I would decide on your business model firstly...
I recommend the niche site marketing biz model, as you are building sites that not only will create their own revenue stream, but also become assets in the long term, which means you are actually building real wealth for the future.
Basically I would do this:
1. Get the free trial of Market samurai
2. choose any general niche idea, brainstorm for 1/2 hour if you need, and build a list of seed keywords (any terms here you don't understand you can google for)
3. put them into MS, and let it find you 800 related keywords, then analyze those keywords, and filter them so that you have Exact match SEOT matching or above 50 per day, SEOTC below 2000
4. Be sure to check the competition, using MS (there are many tutorials from the noble samurai guys and others, regarding what to look for when analyzing comp)
5. Also, before proceeding with the keyword as a possible winner, be sure to check for whether or not the .org, .net, and .com domains have been taken already (if they have, someone or several people are already on it) I use the below for easy checking of the main TLDs:
Code:
http://instantdomainsearch.com/
6. get an adsense account, amazon account, etc, depending on what niche opportunities you discover (adsense is the easiest to monetize non product niches)
7. buy as many .info domains as you can, 1 for each great low comp, good traffic keyword you can find. eg, if your keyword was "the best digital camera to buy", you would purchase thebestdigitalcameratobuy.info (i recommend namecheap registry)
8. start writing articles, choose the top 4+ keywords related to your site with similar good traffic, low comp attributes
each keyword will become the main focus of an article, aim for 4-500 words, and keyword density around 1%.
9. get a baby package at hostgator hosting, you can get the first month for like 1c, and then it's $10 per month
10. install wordpress on the root of each new domain you have bought, making the name of the site the main keyword, the keyword in the description, etc (you can read up on info here on how to best optimize your wordpress blogs, which plugins to use, etc.
12. then make each article a page on your blog, the main keyword article will be a post for your index. (use BM keyword link plugin, and link all your target keywords back to the index as do follow)
13. start link building (again, tons of good info on here on SEO and link building)
That's it, it's a proven business model, and if you do it you will start accruing money from your successful sites (not all sites are winners)
I have been doing this for 2 years now, and the income keeps building the more sites you get out there..
Take action!
Note: mad.hat does have a valid point about .info domains, they are weaker in SERPS, but again, I was just relating this info to you based on the fact you have a minimal amount of funds. I would always go with .org as #1 choice, .com #2, and .net as #3 choice, in terms of SERPS power.
