Wireless assistance requested

[ICXRa]

I have been asked to find a wireless device for work that will mainly be used for 1 or 2 users and maybe later down the road upwards to 10 - 15. I would like something that has a dhcp server due to the fact none of the employees know how to configure their network cards and they are coming from another of our offices that has a dhcp server. This would be running on a private network where the datacenter I run is all public IP's. I intend to upstream this connection on a vlan on an Extreme Summit 48 but and security is a major concern of mine because I don't want anything running wild over our DS3. I would like suggestions as I don't feel comfortable using a soho wireless AP or router for this purpose.
