Boekhouder gezocht for advice about Dropshipping and e-commerce activity

Bedrijfsvorm: eenmanszaak/zzp

Toelichting: Hello,
I want to register activity in your country. We are living in the Netherlands with our family for two years. Me and my husband both have a job. We are registered here. And we want to earn extra income. I would like to register either Eenmanszaak: sole trader or Vennootschap onder firma (VOF): general partnership. The activity would be e-commerce through the ebay platform. Buyer from anywhere in the world purchases goods from me, I order that item directly from a Chinese seller and send this product directly to my buyer. The goods from China travel directly to my buyer and do not reach the Netherlands. This business model is called dropshipping. The planned revenue would be between 15,000 and 20,000 euros a year. If it succeeds, this revenue may be higher. Profit is 10-25% of the income received, after deducting the cost of goods, ebay and paypal fees, currency conversion (because buyers pay dollars).
So I have some questions:
1. Are such activities registered in the Netherlands?
2. What is the income tax?
3. Are there any additional social security charges? (both me and my husband pay the health insurance fees)
4. Do you have a VAT charge (the goods do not reach the Netherlands, they are bought in China and immediately sent to the buyer in any part of the world, and what if there were some purchases from the Netherlands).
5. Is there a sufficient order book for the goods to be recorded on the goods, the cost of the item and the details of the buyer? (Since the purchase is from the retail china they refuse to issue invoices for each item)
6. Do I have to issue invoices to my customers? Will a booking order be enough?
7. If business does not succeed, would it be easy to close these business forms of my choice?
8. where can I address if there are any questions?
I am looking forward to your reply as soon as possible.
If you are comfortable, you can send an answer to my e-mail vkvedariene@gmail.com

Thank you,
