Where have you done your hours building to date? If you approached them they may have an opening if you were to do the course. Another good way is to work for the place you do your FI(R) rating (if they'll have you

).
Me, I worked for a club where I did my hours building. It wasn't the best of arrangements but it has given me some experience upon which to move.
I think that most schools would give you a try as the regular supply of instructors passing through the 700hr route is drying up. The key, however, is getting the rating and doing well on the course.
That having been said there are some schools which will suit better than others. The way a school allocates students to instructors for instance, do you need floats to use the airfield in winter, etc.
It's one of the best ratings you'll do in terms of polishing your flying and will also teach you loads once you've got the rating. I'd recommend it to anyone.
I didn't notice from your profile whether you'd done the commercial exams or not, because you do have to have done them.
