Can someone please offer me some tips for this level? I have tried about 60 times and the highest I've gotten is $2300. I have tried giving all the customers their orders then collecting all the money but with the next round of people I end up getting overwhelmed and I lose customers. I'm about to totally give up! HELP!!!

I feel you, are you still stuck? This is no fun :(
Let me know if you got any advise

That's exactly where I'm stuck!  The highest I've been able to get is $2630.  Same problems as you...it's been almost 3 weeks now.  Very frustrating!

I'm hopelessly stuck here too.  Not even close to goal. I guess we have to practice really hard at getting faster. Any ideas, anyone?

I just passed this level. The posts above me are old but in case anyone else needs help making goal with this level, wait on the most impatient customers first.  Keep choc sauce stocked on the table for easy reach and in case you need to serve 4 in a row.  Chain every single action: clicking out menus and picking up money. The blimp counts as money picked up so I served it last and while still making it's order, I picked up all the money on the counter so new customers can arrive. Just be sure to serve the blimp order before clicking on any of the menus.  If you miss a chaining action by accident, restart the game.  I don't think it's possible to make goal without every single chaining bonus. These tips won't get you expert score but will pass the level.  The goal is the same on level 60 as this level.
 
What I was doing wrong here in the beginning is that I was leaving money sitting on the counter while finishing the blimp order. Don't do this because you can't fit enough customers in.  Pick up the money while finishing making the blimp order.  Hope this helps some of you.
