Unfortunately there isn't a single American product that at this time would stand a chance of winning any competition for those specific users.
No American made and designed helicopter can compete with the the A.119 and the A.139 (really) or A.109E in their respective categories.
As a matter of fact, Bell is now building some of those under license. Now, THAT's a tough reality the American Industry has to deal with.
I'll give you though, that some of Italy's public use fleets (Forestry Service, National Fire Fighters and Finance Guard) have largely outgrown the practical use of their aircraft with the addition of totally unwarranted types, or when those types may have been acceptable for service, they were equipped way beyond acceptable standards.
