White label ETH staking pools

Hi folks,

I am looking for a partner (preferable that is yet for a longer term in the scene) that is providing whitelabel ETH Staking pools.

What I specifically need is a protocol / organisation that has whitelabel pools available to implement on own web via API or similar, whereon I can set the rules i.e. conditions of term, withdrawal fee and so forth.

Tried to look around on the web but nothing of this specific is really findable other than stuff like Rocketpool and standard staking protocols. Recommendations are highly welcome.

In short words, I'd like to open a business, with staking pools from proven 3rd parties integrated on my web. I am not looking for developers or similar to create such, simply as I don't have any smartcontract / pool coding knowledge and can't judge whether they are trustable or not. I want to offer services to clients, based on good names in the crypto era.

Thanks for any information provided.
