Dropshipping on Amazon, do I use the individual or professional?

I’m planning to sell on Amazon, I have a wholesale supplier who will ship products for me on my behalf rather than keeping all at home, they also send products within 1-2 days, return address etc. all in my address, which is required by Amazon, I am unsure whether I am supposed to go straight for the professional account which is £25p/m in the UK or the individual one? The amount of products I will sell are limited, less than 40 for now then add more over time.
