Welcome to the forums @Dragon8 . Really awesome to have you here. Also Dragonite is a great species and may provide a nice and healthy collection challenge, also considering you are going for all PSA10 cards
I would really advice you check out the species collector thread on the forum. A lot of species collectors really help and give out great advice when you ask and you can also find some Dragonite collectors.
There was an E4’s favourite Dragonite also hosted so it might inspire you.
There is a lot of info which you can peruse and unfortunately I am not a species collector so I cannot help much. I just like Dragonite. You can still always ask questions here or on relevant forums and a lot of more knowledgeable people will always help.
Are you collecting all languages or only few languages?
Wishing you lots of fun in the hunt and looking forward to your progress.
