I offered the $300. I agree with Spade. Plurals, in most cases, hurt .pro. I paid $1,800 for Rates.pro and that's one of the few keywords where I think it works OK. The problem with the "s" on Financial is you lose the employment angle of "Finance professional" or "Financial professional".
You could put together a site to download company financials, the problem is how much effort would that take and how much money are you going to make? Plus, the information is already freely available on each company's own site to download.
dnou you wanted $1,000 for Financials.pro initially but I paid $1,000 for Company.pro and that's got 1bn Google uniques and more angles. I've been offering to buy .pros on another thread and the problem is people want huge multiples of registration fee for average keywords. You can still register excellent keywords that work with the .pro extension so it's difficult to justify the premium pricing for now.
Yesterday I registered Democracy.pro (as in Pro-Democracy movements), HumanRights.pro (massive growth area in Law), Chauffeur.pro (you know how chauffeurs like to wear hats and uniforms to make themselves look professional and justify premium pricing), Trucking.pro & Haulage.pro (US and UK versions of same terms, would look great on the side of trucks, more memorable than the usual "J Bainbridge & Sons" you see on highways and motorways), Delivery.pro (as more goods get traded online, the number of delivery companies will mushroom), and Password.pro (1bn Google uniques and encryption technology is only going to grow in importance)
While you can still register .pros like this for $100 and people let premium keywords expire because it's too expensive to reregister it's difficult to justify paying more than a small multiple of registration fee unless the keyword is exceptional.
