The debt service alone on $2,000,000 is enough to guarantee failure unless the format is moderately successful. Add in extra debt for capital startup costs and operational expenses and you have a situation where the format needs to be spectacularly successful. With that kind of loading, an alternative format probably cannot derive enough listeners to pay the bills. I'd look for a low maintenance, mainstream format that plays well in businesses. I've no idea what's on the air in town, but a format something like smooth Jazz/light AC is one possibility. Oldies might be another. Classic Hits or Classic Country would also be worth considering. All have the advantage of being easy to program and maintain (think low operational costs), all can sound good in a business environment and they can each draw decent numbers.
Now, if you can get the station at a good cost, say under $500k, then your format choices are broader because you don't have to be as successful to survive. You can, as a labor of love, play an alternative rock format, but keep in mind that the format has to be kept fresh an interesting to work. This requires you to spend your days updating the playlist instead of the #1 job which is selling, or you have to hire knowledgeable staff which is an expense.
I suspect that that survival for the lonely standalone in PCF probably hinges on a strong local sales effort with low rates targeting mom & pop businesses that cannot afford to pay corporate radio rates. Be prepared to hit the streets with a $20 rate card and be willing to negotiate way down from there. Probably, you'll have to pay a larger commission, too or else your sales people will starve. With luck, you should be able to pull in $25k to $50k per mo. if the sales staff is very good. Every expense has to fit within that budget or one day the bank owns the station instead of you.
