Does this paragraph seem correct from a grammar standpoint? Is the message clear?

Hi
We're going to merry at the beginning of August. Our intention is to stop guests from spending large amounts of money for flowers. It would be much better to transfer these amounts to a charity fund. That's why all invitations will be followed by a small card with instructions and explanations. Can you please help me to validate the text below? I want to make sure there is no grammar mistakes and our message can be easily understood by everyone

Thank you in advance!

We'd appreciate it if you transfer money which was supposed to be spent for flowers to the following bank card: xxxx-xxxx-xxxx-xxxx.
All incomings are to be donated to the charity fund "Starenki".
