Hi sir,
I've already done a lot of automated task involving scrapping website data like you want to do.
I also worked with a lot of captcha breaking services, which I recommend by the way. GSA is not really accurate for its price but if you want to go this way it's your call.
However, I worked with DeathByCaptcha which is a solving service made by HUMANS, its really accurate, kinda fast and cheap (1.3$ for 1000 captcha), I could even hook you up with a test account.
Thanks for your time.
