Ask HN: business registration and banking as a service?

So, my friends and I have made this web service together. It started as something we were making for ourselves, but soon more and more people found out about it, and now we already have several thousand users. Some of our users are asking for a way to donate money to our project, and we could really use that money to cover our increasing hardware cost (we will likely soon need a second dedicated server just for this project alone). We thought of implementing paid accounts, however we are not sure how to organize the whole financial part properly. As I understand, to accept money from our users legally we need to be registered as some sort of company, and pay taxes. Nobody in our team knows how to do this, and, to be honest, we enjoy writing code much more than getting into those legal details.

The only easy option we see now is to receive user payments to a personal Paypal or bank account, however this will require us to pay taxes for all of that money, even though we will be spending most of it on servers and will be making zero profit.

Has anybody heard of a service that would allow us to open something like a virtual business account? We would need something that will:

- allow us to get money from our users to some sort of an account;

- allow us to pay for our servers from that account;

- in case our revenue exceeds expenses, pay proper taxes for the profits we make;

- allow us to withdraw post-tax income to our personal Paypal or bank accounts. We will then deal with personal income tax just like we do on our day jobs.

Has anybody heard of a service like that? We would appreciate any other advice as well.
