Hello,
My name is Rui Pimentel and I've more than 8 years of experience in development of web crawling and automation tools.
I understand you've had some bad experience on freelancer before, it happens a lot around here, I'm sorry you had to experience it, but I can assure you I'm your man, I have my mouth where my brains are.
I've added you on s_k_y_p_e, let's chat soon because I don't fully understand what you need yet, but my vast experience allows me to be relentless in search of a solution, I won't make you lose any time and won't ask for release before you 100% happy with the results.
Thanks,
Rui
