My brother has just been found guilty 7counts of fraud.How long could he go to prison for?

I am hoping he gets commuinty service as this is his first offence. His offence is that he opened a bank account and gave the details to a criminal who in turn laundered money through his account. A stupid and naive thing to do but then that is my brother.He pled not guilty but the jury did not believe that he knew nothing of what was going to happen with his account. He wants to appeal but then that is upto him. He is 21.
