I need a roblox develepor

Hello, I just started designing a game today and wanted to see if you could look at it, This is just the basics of what im going to work on and there will be more added tomorrow, I just wanted to see how much it costs for you to make a game like this and if you could in the first place. Another question is if you can show me other games you have made so I know you are good at what you do and im not ripped off, but here is the basic idea. In this game you start off with your raw power to defeat weak but human sized slimes, there are 2 types of these slimes in the first zone with one being red and
one being green, From killing these slimes you gain exp and coins. overtime leveling up will give you a random crate with some giving you great items and some being
trash, but with coins you unlock different areas and pets that give exp multipliers, coin multipilers, and damage multipliers. Only the first area has this slimes with other areas having different kinds of mobs. Every 5-10 minutes there will be a battle arena that you can join and fight other users at. The gamepasses include triple open, fast hatch, teleport to unlocked areas. Gamepasses that you buy multiple times is 2x exp for 30 minutes, 2x coins for 30 minutes, can buy coins, can buy exp (more expensive than coins as its hard to get). This is all I have planned out right now but if you need any extra info i will give you it tomorrow morning as its late.

The game doesen't have a name just yet but im thinking of one right now
