Highly recommend D.I.Y.
I know, if we do that then why bother do what we do?
As a human consuming & distributing garbage we feel we all will have too pay more in our dues because of how much we don't pay into our solutions,
together the odds are in our favor,do it your self for as long as it takes then it can be free,want it quick then it will most likely cost something,become a good wheel and dealer and put everything together and just make it happen aside us being able to do it for you, we could and will but we promote the best of ones well being even if it takes sacrifice's of our own accord. The more someone can learn then the more they can provide fish;0)
Aquaponics is very variational with one simple idea implemented,When fish meet the garden.
All you need are the basic's Barrel that holds fish,containers that hold medium & the plumbing.
If your not to inventive then start small,we don't want to hurt any animals learning so start by what ever means you have though just seeing if it will work.
Get yourself custom to the symbiotic relationship on how it works and then begin by building what you can,even if its just water flowing.
The most important thing is to have a strong mind,Know your aim even in hard times don't give up because this is something that will reward you. 
Just remember when your building that there are many different concepts out there.
There is no one way, the only thing stationed in the idea is the plants,fish&timing everything else from that is your creation.
It can go as far as to have edible fish,plants,shrimp,solar panels where it is COMPLETELY self sustaining through batteries and pumps,also within your creation
I recommend air in the bed,aeration of the very roots.Your plants will show you how much they love it & you will too :0)
