A ton of Questions. Please help me.

Hey there everyone. I’m completely new to this whole toppic of Amazon FBA and to be honest I actually thought it was just another Method those „Gurus“ use to get rich with nothing. But I did a ton of research lately to complete my Business Plan and get the Money I need to do it. But I still have some questions I didn’t find an answer to. For example: How many Clicks do you actually get and how much does your PPC cost? I’m planning on niche private label products with estimated sales of a few hundred to a thousand units a month, so I guess not more than 5k views, right? And as I want to ship to Germany: Are there special certificates or regulations I need to know? Or a place where I can look them up? Found nothing about it yet. Another point is shipment. I found for 3.000 kg a price of like 2.200€, does that sound right? I found it a bit expensive but could be just my lack of experience. Another big question mark are freelancers. How much do they take for photos and Videos? Yeah I know, a lot of questions but I need to get this right since I have no money on my own sadly. I hope you can enlighten me a bit. Thanks for that in advance and have a nice day.
