I will create a friday night funkin chart for you

In that case, there are two options: You can make separate orders for each one, or message me directly and I can set up a custom order for you to include all of them, the second option being prefered in most cases.

Contact me directly and, depending on the length of the song and some other factors, I will determine the price and delivery time.

Yes, although it would have to be a custom order.

No, those will have to be provided in order for me to make the chart. (Original sprites are, of course, fully optional.)

If you're unsure of this, you can message me directly and I'll try to help as best as I can, before or after the order has been complete.

Not likely, as I have very minimal experience with creating .lua files. All the Psych Engine events I use for my charts are the ones that come with the engine or have been made by someone else for some other mod, otherwise they'll have to be provided beforehand when the order is made.
