Looking for Business Bank Wire service

Hi,

Hope this is in the right thread to post.
I'm looking for something very simple. We have to pay an outstanding balance on a secondary account to an ad-network where we already have an account with under our company.
So ideally we are looking to wire the amount to a secondary company that can then in order pay off the balance to the ad-network. The amount is in the low-mid 5 figures and in Euro.
You can invoice us and we pay you the amount to which you just wire the amount to the ad-network ( we can probably ask for an invoice from said network )

If anyone can provide such a service please let me know. We can pay a % on top of he amount needed to be send.

Thank you in advance

Destination bank account is in the UK and bank is HSBC. Percentage we would be able to go between 5-10%.
