Hi Loza,
We got married in Cyprus 3 years ago. We got married in a large hotel so they had their own wedding planner who helped us with everything, and we arranged the whole wedding via email!!
It definitely ended up cheaper than a wedding here. It was a five star hotel with 35 people and we spent under £7000 and it was possible to do it cheaper than that depending on what options you choose.
If you tried to do it yourself I think you would be overwhelmed by the options, not knowing which were reputable companies, and trying to co-ordinate the whole lot. It would end up being a very stressful full time job I think! If you want to get married in the Town Hall then have a reception somewhere else, there are lots of independent wedding planners who can help you do that too.
The beauty of a Cyprus wedding is that the minimum residency period is only three days, you can get married in any hotel on the island as well as the town halls, and its fully legal over here so no need to visit a register office as well.
We found the weddings abroad forum on You and Your Wedding website to be absolutely invaluable so you might want to head over there.
Any questions, let me know
