Munly Leong keep in mind for future postings the job board is merchant|hiring focused*. Service providers benefit from restraining advertising here to avoid reducing the boards utility to merchants because as the more providers advertise the more likely legitimate merchant posts get drowned out.
To find partnerships, join the shopify partners program(signup), and reach out for contacts in the job partnerships forum available only to partners. Neither of these routes guarantee success.
If your looking for freelance work be sure to subscribe to the job-board itself to recieve notifications of postings.
*At this time there is no clear place to post-topics on 3-rd party business offerings that are not app related. So subscribe to boards of interest and offer services to merchants that are actively seeking help but may not be sure if thier issue is a job.
