I think to grab more users to try out your designing services is to publish online your portfolio so they can see what is the forte of your sister's design and how it would be beneficial to any users that would and might inquire on your services in the near future. Having a good thread design is good as well yet you must atleast be Jr Member/Member to publish images so you can have a much appealing service thread. I am a designer myself as well yet ironically, I don't publish my portfolio since most are with private negotiation. But these suggestions might help you out.
You can also upload photos in imgur and just post the link here and let me or other user's quote it for previews.
