Island Air, I appreciate your enthusiasm. However, you may find that such enthusiasm needs to be tempered with a little realism. Unless you're operating only Islanders and Twotters, it will be difficult to make a go of scheduled services. As 10W says, the weather (apart from anything else) is problematical. Terrain will make installing an ILS difficult, and you need the business to pay for it. If you merely provide an NDB or a LLZ approach, you are unlikely for a lot of the year to get in.
You need transport links to local towns (Oban is rather more than a 5-minute stroll away).
And finally, you need to convince aircraft operators that they can make a go of such an unfriendly "hub".
Good luck!
