Hi. I'd say, you should likely do this job yourself.
Even if you aren't a coder, it's likely going to be very simple to get it up and running how you need it.
I'd take a look at the code here:
https://github.com/walletgeneratornet/WalletGenerator.net, and likely only a few modifications are necessary for that.
If y'all were interested, I could, however, set you up with an online hosted wallet for your coin. That one is a bit trickier, but quite worth it, having a full wallet online for your users.
Let me know if you are interested.
