Raspberry Pi Tunnel Bear VPN wireless access point router

I have a Raspberry Pi B running Debian Wheezy and equipped with 2 x EW-7811UN USB WiFi dongles. I have attempted to follow guides I have found online: [login to view URL] [login to view URL] I constantly encounter problems with setting up the RPi correctly. I have the hardware but I now need someone to either guide me on remote access to my RPi (best) or to Download the Debian Wheezy installation and install the hostapd etc so that they create a custom RPi disk img for me to download and install on my RPi. I will also require set up of my VPN service (supports OpenVPN on Linux - Tunnel Bear). My desired end state is to have a RPi that connect to any wireless network including free wifi at cafes etc, running my Tunnel Bear VPN, so that I can connect to a secure internet connection. Cost to be no more that $150 - I can always buy a fully set up NetNinja but prefer to use my own equipment.
