The time it takes to create a character model Thread

I'm in the process of designing a game that has a play time of roughly 4 hours, my main role in making that game is programming, bit of 3D modelling and putting the game together. My question is what is the average time it takes to create a textured character model with basic animation? when working on two previous project, once it took a month, and the other time it took 48 hours straight. I want to get a good idea so I can balance the playtime of the game with the length of development. The quality of the models that I have in mind at the moment is something like Team Fortress 2.

The animation will take way longer than the model itself, you can generate static high quality models with Make Human in blender. However, getting a good skeleton and setting up natural looking motions will take longer.
