Alex;
Seriously (very seriously) there are quite a few threads like this one in the history of this forum. A wedding is a high pressure event for those involved, you need to ask yourself (and any pilot) the following questions:
1. Is the landing site appropriate and has the aircraft the performance to fly in or out of it?
2. If a pilot volunteers to help you will he have sorted out all the potential CAA traps of Rule 5 etc?
3. If the weather craps out have you a back up plan?
4. You are offering lots of coverage, website stuff etc, does that constitute a payment for flight under the terms of the ANO?
5. You are probably hoping for the generosity of a PPL forum member (no AOC would take on these terms) does he have the experience you want to transport you and your bride to where you want to go?
6. If on the day the heli goes U/S are you going to take that on the chin? or are you going to put a lot of pressure on? see also 3 above.
I hate flying for weddings, people do stupid things around aircraft (at one hotel 200 guests ran at the helicopter while the blades were turning, god knows how no-one was killed) Photographers ask for things which may not be sensible and put more pressure on the pilot and the pilot may do things, he normally wouldn't and put himself into a situation he can't get out of without making a mess of the aircraft or pax.
Good luck with the wedding, seriously go by Bentley, its' easier and a lot less hassle.
