To get the right answer you need to ask the right question...
The length of the copy is not the issue.
You need to get out and talk to some of your clients.
Find out what it is that makes them use your service.
Find out where their hot buttons really are.
Then put the biggest one in your headline.
Most important of ALL you need to develop an enticing offer that makes people want to sign up for your meals or at the very least contact you immediately.
Let me give you an example.
Let's say you help each of your clients put together a customized meal plan - including the meals they eat that you don't supply.
That's a valuable service worth $50-$150.
You can tell them if they call you right now you'll give them this first service free.
You need an offer that get's people to contact you.
From there you have a chance of converting.
There's more but without a well thought out, enticing offer you'll find it very difficult to get people to make that jump from the website to contacting you.
Kindest regards,
