I'm not really good about this and I'm just assuming this number but I think around $1000-$5000 but here are the list you needed to pay:

1. Smart contract
2. Team member
3. Website creation
4. Graphic designer
5. Whitepaper/Proof reading creation
6. Legal contracts/documents (depends on the the project)
7. Promotional/advertisement
8. Future Development

There's a lot of thing you need to consider and pay, creating/developing a coin or project is not easy as it is and not just money needed, you need to have  good and skilled team members.
