Hello mate,
Unfortunately I think you'll be paying around £1500 for a standard/stage 1 Escos which is about right for your age, although the area you live in can make a huge difference.
I'm still paying 1k and I'm 28 with 9 years NCB.
Try calling these two companies for really good quotes:

Good Luck mate
