Thanks for your help 

Its modelling and acting we're looking for- i thought they did both!
oo good thing i read this i was swaying towards eka because they seem really nice on the phone, have a good client base and iv heard they are at alot of castings but iv also herd they take on everyone! 
Tuesdays child and little allstars have met her in person but little allstars want us to sign up to them as a sole agency for 3 years :/ which is a long time if they do turn out to be no good!
THe other two have just seen pics.
i will try the others you mentioned i heard KIds London were good but not heard of KM branch getting many jobs
URban angels is one i really wanted to go for but their books are closed for a while yet
