Thanks for your concerns, @connecteconomy, there are two reasons why we have a closed group as of now:

• We have been producing content for our clients and to keep their privacy in check, we deal with only a few selected professionals.
• To avoid spam and maintain content quality.

To target larger segment of STEEM we generally have open(available to all) tasks such as this one. As @leotrap suggested, please participate in these and we might pick you up for a job that requires your skills.

We are also preparing a v2 of the platform to support more users! SO hopefully in near future we might approve more applications.
