If I am not otherwise employed by another client we can certainly speak about your requirements, sure

A general misconception is that making a game is easy, takes almost no time and is cheap to make. All three these things are false. 

How long a game takes to make is entirely dependent on how complex you want the game to be. Building a Pac-Man clone will take very little time.

Building a better Fortnite will take longer…

My normal rate is $3,000 per month. Depending on the complexity of your game it can take between 1 and many months to create. 

Again, how long it will take depends entirely on how complex your game is going to be. Please see question 2…

Unlike normal where a developer quotes for a specific amount of time and then works to that budget and deadline, I work quite differently since I do this both for fun and work.

I don’t block out “This will take that long and this will take that long”, then bill accordingly and hope my estimates were correct. Instead, I bill “per period of time or part thereof” and then I usually go over that period and do unpaid overtime.

For example, if you hire me for a day I will bill you for 8 hours but will work for up to 20 hours to get everything perfect. When billing per week I bill for 40 hours and if that time is up after day 2 then I work for free for the rest of the week. My record so far is 68 hours for a week

So, yeah, I don’t work by time tables. I just work by day/week/month
