You'd be massively surprised at the levels of pay at certain clubs from step 5 upwards..Yeah the league varies massively. The 250/300 will be what Aveley/Taunton and a few teams will pay. The upper scale is definitely tipped with Yeovil coming down as well as Maidstone and Torquay. Dartford also pay quite a bit.
