Developing a stretching plan

Hi everyone, I didn't want to put this up as I've seen a lot of them, but I'm really struggling to create a good stretch plan for what I want. I've read a lot so far and found http://www.fightingarts.com/reading/article.php?id=256 helpful. I've read up a lot but somethings seem to make little sense to me and I just want a black and white stretch guide. I've been reading up here http://www.trickstutorials.com/index.php?page=content/flx3#ddf_5a but again, I'm unsure of what to do to achieve my goal.

I want to be able to kick high, but keep my foot there for another kick. I can already kick fairly high but lack the strength to keep it there.

I also lack a partner to do PNF as much as I'd like to so I'd like an alternative.

Many thanks

Every time this subject comes up, I think about the Pilates reformer. Unfortunately, Pilates studio time is expensive. Even a home reformer costs thousands. And yet, dancers who have to keep their legs in odd positions use this device for flexibility and strength. It couldn't hurt to look around for a studio that might have a holiday deal going.

Thanks for your reply, that machine looks medieval. I'm currently aiming to work on dynamic leg swings, with (type of stretching) contractions. Throughout the day I work my kicks and holding them at their heighest point
