I recently found this video on youtube where matt cutt's describes how he would start an online business with only $10..
he mentions how he would buy a domain and webhosting, in my opinion that seems a bit of a waste... You will loss all your money right away and you basically have one month to succeed or fail...
In my opinion i would set up a free wordpress.org blog or blogger blog as it would save quite a bit of money and you can spend it on link building.
just wondering what you would do!?
