Learn Turkish: Bulacağımız fotoğrafçı ve müzisyenler pahalı olacak. - The photographer and musicians we will find will be expensive.

This is the future object participle from the current lesson. It is built using the verb stem bul- (to find), the future suffix -acak, and the possessive suffix -ımız (our). The k softens to ğ because it is followed by a vowel. Literally, it means "our future-finding".

Does bulacağımız describe just the photographer, or both the photographer and the musicians?

It describes both. When a modifier like bulacağımız comes before a list of nouns joined by ve (and), it applies to all of them. So it means "the photographer we will find and the musicians we will find".

Since the subject is multiple people, why is the final verb olacak instead of olacaklar?

In Turkish, if a plural subject is human, adding the plural suffix -lar to the main verb is optional. Leaving it off and simply using olacak is completely grammatically correct and very common in everyday speech.

The suffix -acak appears twice here. Are they doing the exact same grammatical job?

Not quite! While they both relate to the future, they have different roles here. In olacak, it is the standard future tense marker for the main verb ("will be"). In bulacağımız, it acts as a participle, turning the verb into an adjective to describe the nouns that follow it.
