blockchain game development

Hey, I am a team member of a meme coin project. I will share with you all the details later if you think you can do this job. We are looking for someone who can develop a play to earn game for us. Do you have experience with that? If yes, what are the approx costs for a simple game for iOS and Android either jump and run style or tower defense style. How long will such a development take? Looking forward to your answer!
