I will be dungeon master for a homebrewed campaign

No, unfortunately. I have had many years of successful campaigns with my homebrew style and many happy players. I know my own system much better than any typical edition of DnD as I have spent many years perfecting it and improving it.

As much as you would like. I typically play DM as a sort of storyteller reading a book about the group of adventurers, but if you'd like I can do voices for characters/NPCs and have interactions with you the player.

If you are intending to play longer amounts of time or wish to have a longer running campaign a better price can be discussed. Any other specialty things you might want can be discussed.

Usually a maximum of three hours. However, if you are wanting to play longer we can discuss a date and time that works for everyone.

Never Fear! I make notes as I am playing so that your individual stories and situations will not get lost. Apologies if I get a name or two wrong though.

In most instances no. The first three sessions being set at a lower price are just to give the customer a way to try out the game at a cheaper price and decide if they would like to play long term. If i decide to, i will offer special allowances, however do not expect that as the standard practice.
