Developing a coin and building wallets are different things.
The usual fee for compiling win/mac wallets is around .1 at most and if someone is asking more,
he's ripping you off.
no one offered me , I just saw a topic on the services section and people was actually paying that amount to do that . It's weird how expensive is it , pretty sure you can found someone who can do it for free on programming forums .
