Best Configuration GSA SER

Hello friends,
I am new to the GSA world.

I would like to know from you what the best settings are for linking to money site.

I made a project and let it run for 12 hours, and only had 6 links submitted and 3 links checked.
I am running a new test, with 20 private proxies and buying a few more captchas.
Many people indicate to acquire already verified lists, do you use ?
What are the best configurations?
I would like some tips from you for a beginner.
Thanks a lot!
