Modify very short HTML code to add some features

On a web page I have the following code. It's the only code on that web page. It receives the values of the @virtual fields from the page before it. This code then prompts "PRINT REQUEST SLIP" and when clicked, sends the @virtual field data to an app called Rawbt that prints it. This code works the way it is. What I want, is for the code to NOT show the prompt "PRINT REQUEST SLIP", and just do the printing as soon as the page loads. When it does that, I want it to put a message on the screen that says "Thanks for your request. Please be patient and wait to be called to sing". I would like that message displayed for X seconds (I can change that value in the code later) and then go to another url (Just add some url and I can change it later). I'd like to be able to resize the font of the message in the code by changing the value in the code as I dont know how big I want it yet. The HTML is as follows <a href="intent:[@Virtual4] - [@Virtual5] - (SINGERS) [@Virtual1] - [@Virtual2] - [@Virtual3] #Intent;scheme=rawbt;package=[login to view URL];end;"><font size="+2">PRINT REQUEST SLIP</font></a><font size="+2"></font><br /> &nbsp; Again, that code works the way it is. I just need the features added that I asked for. If you don't understand what I am asking for please don't reply with a thousand questions. I have explained this perfectly. If you can do it for $20 or less in a day, you are the person I am looking for. There are no files to send you. It's just that code. Thanks
