Project for Sigun -- 2

DO NOT HIRE THIS PERSON! THEY DEMAND MONEY UPFRONT AND AFTER SEVERAL WEEKS OF STALLING THEY HAVE DISAPPEARED. I LEARNED MY LESSON ON PAYING UPFRONT. THANKFULLY I WAS SMART ENOUGH TO ONLY GIVE A DEPOSIT AND AM ONLY OUT 10% OF OUR AGGREED UPON PRICING. HE ALSO INSISTS ON PAYING VIA WESTERN UNION TO AVOID FREELANCER CHARGES. THIS SHOULD OF BEEN MY FIRST RED FLAG. PLEASE DO NOT HIRE THIS PERSON. SAVE YOUR MONEY AND SANITY.

Small PCB review

Sigun was very communicative and explained everything in detail. He delivered on a very tight deadline. I'd definitely work with him again.
