Hello,
You are going on the wrong track in making money with blogspot.com.
If anybody could help you make money and share 50% profit only for 1st month and leave your site's profit from 2nd month onwards, then why wouldnt they make it themselves in the first place?try to use your head.
You can substantially make some money around $7/mo to upto max.$40/mo per site on lazy way(without doing anything) but by providing online services whose setup you need to carefully plan and then do it. This way your growth in income is stable, otherwise you will only make $30 in 1 month and next month you make $0. So take our advice for stable growth.
