At this point we are looking for a crypto exchanger / crpyot exchanging service that will exchange SEPA transfers to cryptocurrencies for us. We only work with larger sums and are interested in long-term contacts.
If you mean by us, a business that receives and sends thousands of dollars per day, I do not think that most platforms will meet your conditions, there are markets called OTC market and accept these requests at prices ranging from 50 thousand dollars per day to several million dollars.
But if your activity is less than this, I do not advise you to register yourself as a commercial company due to the many legal complications.
