Install FreePBX or Similar Asterisk PBX Server on my web linux server

I don't want to use RinCentral anymore, and want to have full control of my own PBX server. I would need someone to install an Asterisk PBX based PBX system on a linux based web server. FreePBX seems like a good option, but I am open to suggestions. I have a very simple set up. Around 5 phone numbers are used for business. Customers call these numbers and then go through a voice prompt hierarchy. During business hours, it will ring simultaneously my house phone, office phone and cell phone. If no one picks up, it will wait 5 seconds, and then simultaneously call the numbers again. After 3-4 minutes, if no one picks up, the call will be sent to voicemail. If 2 or more customers call at the same time, they will be placed in queue. Only after the first call is done, will it start simultaneously ringing the lines again.
