If you want to lease SP from people (via delegation) then go to http://www.minnowbooster.net/ They have a very good marketplace and are very upfront about their rates. You can also join their Discord server (link) and get online help. Tell them I sent you :) I might even so you there.
Currently: the prices are:
Lease price 1-3 weeks 1 STEEM ⇔ 75SP (per week)
Lease price 4-24 weeks 1 STEEM ⇔ 150SP (per week)
So, if you want to lease 150SP for four weeks then you'll pay 4 STEEM total.

Oh thank you
