Andy, some info for the fence I have just put up that may provide some help to you - I hadn't done this before so I was a novice....the fence is approx 36metres and has a sloping section. Some links at the bottom.
Basic Materials bought from local timber merchants:
20 of 100mm*100mm sawn tanalised posts (£6.30 ea)
10 of 25mm * 150mm sawn tanalised, 3.6m (£2.88 ea)
40 of 38mm * 88mm sawn tanalised, 3.6m (£2.70 ea)
360 of Feather Edge tanalised, 1.65m *125mm (£0.58 ea)
10 of 38mm * 50mm cappring rebated, 3.6m (£3.96ea)
20 of plastic caps (~£5)
2 ton aggregate mix (£74)
cement ~15 bags (£3.88 ea)
Took me about 8 days split over weekends and working with the weather.
Digging holes was the hardest part physically, recommend one of these:

My bays were 1.8m which is probably small but I think it wont blow down! Took the decision to do them half the size of the gravek boards. Screwed the rails to the posts but that was because the cement had not gone off totally. Screwed the gravel boards, nailed everything else.
Top tip: get a good string line and keep it taut & buy a post level.

Generally not many tools needed but useful if you have a sliding bevel and good chop saw.
Big thanks to Thermo as he helped me with all my questions along the way.
Recommend it totally...good luck.

p.s go with the rebated capping as it looks smart!
p.p.s use a 25mm batten to get feather edge overlap and level every 10 or so....I levelled every one which now seems OTT
