Amazon FBA partner - privat label - Long term -- 2

We are an online store (www.tonerweb.no) that sells goods to the Norwegian market. We have existed since 2013. We buy goods from Nordic wholesalers, but sell ink, toner and tape under our own brand which is produced in China.
About a year ago we sent some items to Amazon England FBA as a small test. We learned that results do not come for free. We spent no time following up this test batch and the result was not good either. Marketing must be worked on to obtain good feedback, adjust PPC campaigns, goods should be sold under your own brand, build up frontstore on Amazon etc.
We do not have the capacity for this and are looking for a partner who can manage Amazon FBA sales for us in the future. We are looking for long time partner.
Today we have everything ready for sale on Amazon FBA
- Own brand with good margins within ink, toner, tape and paper rolls
- Good product pictures
- Registered with own trademark on Amazon
- Account on www.gs1us.org for EAN number to products
- Is registered / VAT no. in 5 different countries Amazon warehouse

You must have very good experience with Amazon FBA, the entire spectrum. But especially marketing PPC on amazon and being able to build up a private brand on Amazon.

I think as a start that we only send 2-4 products to a marketplace. For example, Sweden. You list these products and start marketing. In the video link below i explain littlebit how we can set up best text etc. But i can show you this later.
If this goes well, we will expand with more products. Next, we expand to more marketplaces and countries with Amazon FBA.
In order for us to be sure that you are long-term and will give the maximum, we want an agreement where we share the profit.
Sales expenses = profit.
We are responsible for all financing, but share the profit with you. I envision an advantageous of profit with 35-65% where we have 65% and you get 35%. We are responsible for all financing and the products so you have no financial risk.
I want you to have a high profit, because then you will see the same good opportunities and expand.
Made a small video here i talk littlebit about our company products, Amazon seller central.
