Best Methods for Finding LinkedIn URLs Cost-Effectively

Hi Claysters! What do people find is the most cost effective and yields the highest results for Finding a person's LinkedIn URL? I'm providing full name, work email address, company name, country.... have tried Apollo (seems the best, but we are throttled with our hourly API calls), Claygent (fairly good, but at least 2 credits per result), Enrich Person (doesn't seem to match many) Anyone got any great ideas for me?
