How Can I Turn My Windows 7 64 Bit Desktop Into A Wifi Hotspot To Share Internet With My Android Smartphone

I want to spend maximum US$10 to US$12 on the project. This includes buying an USB WiFi adapter and also the routing software.

I am aware of Connectify Hotspot, but it is steeply priced. Therefore I am thinking of EDUP Nano Wireless N 11n Wi-Fi Nano USB Adapter Dongle WiFi and https://virtualrouter.codeplex.com/ , which is a freeware.

I need your suggestion, that will it be a workable solution? Can you also suggest some alternatives within that budget?
