The Mystery at Mockglen (Halloween)- Difficult, looking for 2-3 Players

Looking for 2-3 Players, I already have 2-3 players in the campaign. We were playing a main campaign and it slowed down because 2 people ended up leaving without notice. We decided to switch to a shorter "one-shot" campaign and see where it goes from there. Preferably we start this Sunday, the day after Halloween. Campaign should last around 4-5 Sessions, into Christmas and New Years area. Players will start at lvl 5-7 depending on how many people join the campaign, and we will end at around lvl 12-14. 

"The Mystery at Mockglen-

A jovial and excited group of adventurers approach a normal town, looking for the most interesting, and rewarding of adventures. In a bar, you are approached by a high class looking man, named Mr. Weller.

Mr. Weller claims that there is a problem in a far away town, deep in the nearby swamp- The Mayor of Mockglen is missing! His close friend, Mayor Joe of Mockglen, has gone missing. Mr. Weller will pay very handsomely if anyone can find Mockglen, and save Mayor Joe.

Find Mockglen? You think to yourself, as you ask around. Some people tell you that it's in the middle of the swamp. Others laugh at you, saying that the "town" of Mockglen... simply doesn't exist. Some say you'd be a fool if you found it.

The terrain is rough, unknown spouts of damage will occur, and the campaign is dangerous. There is no tutorial, and dying is a possibility from the start."

I am interested. While I made my character, I still feel very new and this seems like an easy, beginner-friendly starting point.
