Nathanial, you are young and very keen and I hate to dampen such enthusiasm. Believe me that over the years the flying operation has been run as both a business and a members owned club. Both models have their merits -
As a business the management can make executive decisions without recourse to the members but there is never enough profit to give an investor a return.
As a members club the politics and committee paralysis eventually come to the fore and kill the organisation.
The running costs of such an operation are very high and the big variables of weather and unforeseen costs, usually aircraft maintenance, make it very difficult to do anything other than firefight.
It is very unlikely that the airport would entertain another operation but even if they would my advice as someone who has been involved in the past would be to keep well away. You really will be letting yourself in for a grim experience.
The only viable model in my opinion is for one of the more established national flying operations to set up a branch in Cardiff but I guess in the current economy this is highly unlikely.
Remember the old adage that "the way to make a small fortune in aviation is to start with a very large one" - sadly there are many who once showed your enthusiasm who can testify to the wisdom in this.
