So you can design. Now you need some other skills. Like presenting yourself.
Try making a post like.

I can do this and that and that. Im avaliable for that and that.

Now this might slightly increase your chance of getting hired somewhere.
Just a quick tip.
And stop posting stupid smileys with every reply.
