Grazing or D.I.Y Livery in Wellington, Somerset needed, any ideas?

[ellieR]

Hi. I am new here and am getting my first horse on loan in a few weeks. But, am struggling with livery. I live in Wellington, Somerset and have found a few, but, not sure which one (if any) is best. They are:
Heazle Arena
Great Tadbeer Farm
Southey Farm
Millhouse Equestrian Centre

She can live out all year round, so should it be cheaper for just grazing?
What would be the right price per week?
Many Thanks in advance.
