Buy Pokémon cards in bulk during 2007 to 2015 years

Hi, I hope you’re doing well. I’m interested in buying bulk Pokémon cards, mainly from the 2007–2015 era (Diamond & Pearl, Platinum, HeartGold SoulSoul, Black & White, and XY). I’m not looking for high-end expensive cards right now—just affordable bulk to slowly build my son’s collection. I live near Dundas & Tomken, and also work at the airport. If you have any bulk lots available, could you please let me know: Price, Approximate number of cards, and Which era/years they are from. I would really appreciate your help. Thank you for your time 🙂
