I have 430 yugioh and pokemon cards?

How muh could i get for them? These cards are about 5-10 years old i startee collecting when i was 3 and stopped when i was 8. i already found a place that is willing to buy them from me but i want a rough estimate of how much i could get fot each card. I have about 300 yugioh cards and about 130 pokemon cards. 60% of the yugioh cards are common and the rest are pretty good cards. All of the cards are in exellent condition.most of the pokemon cards are very good too, and the rest are elementals. Oh yeah and i have about 500 card holder slots. All the cards are in the slots and i have about 70 left Over. Please answer quick and thanks
