How to modify my GSA?

Hello every one! i want to modify my GSA as much as it could be. i want to add as much engines as possible to my gsa so that it may post on every possible platfor. I am unable to write new engines for myself is there any service to buy?
are there anyother or more modifications that can be done with it. i am considering to  buy Kontent machine for my content will that be the best option?

Any more suggession to make my GSA the best software for automation. I know it is already best but i want more out of it.
What type of Captcha service will be best? will the captcha tronix and gsa captcha breaker be the best combination?

Thanks In Advance for your brilliant advices.
