You can buy the delegation at blocktrades.us or at minnowbooster.net
average price today is 1 Steem for 150 Steem Power per week. Or about 37 Steem Power per month.
But today, after the spike of SBD, it is kinda hard to get delegation on minnowbooster. Blocktrades will take your order and will give you the delegation when your time comes. There is a long queue now due to the increased demand.
