How is pricing determined for drill design?

There are two main factors that determine the price of your design.  
These are the size of your band and the difficulty of the drill. 
Below is an outline of the different levels of difficulty.
Please contact me for more details.

Grade 5 – Advanced
80+ Pages
This drill is suited for highly competitive bands with the necessary
practice time and experience.

Grade 4 – Difficult
60-80 pages
This drill will explore some concepts found throughout the grade 5
category but with fewer charts. This is great for competitive bands
that have mastered the basic concepts and are ready to start
increasing the difficulty.

Grade 3 – Medium
45-60 Pages
This drill is best for groups that have been introduced into the
competitive marching band scene but are still working on their
basic skills or for groups that have limited practice schedules.

Grade 2 - Basic
Up to 45 Pages
This drill is best suited to bands that are just beginning the process
of joining a competitive circuit or for bands that perform at halftime
shows and festivals.

  
How is pricing determined for winterguard and percusion staging?
   
-Difficulty
-Length of Show
-Method - Do you want me to send you the drill or do you want me
to come in and stage the group in person?

  
What is your payment plan like?
   
I like to receive 1/2 of the payment before I start the project but I
understand how school districts/band boosters work with fund raising
and schedules so I am open to most payment plans.

  
What if my numbers/instrumentation change after I give you the information?
   
If you can get me the changed information before I start writing, then
it is no problem. If I have already written the drill, I will make the
changes after my other projects have been completed and for a fee
equal to the additional amount of time the project will take.
