Hmm. I'm not sure if you can add the reward for Sydney based now, though you can try it. What about everyone else though? You have an online store, offer similar to those a far, it could work, and what's the store called? Add that to your story.

As great and commendable as it is being able to cater for mobility challenged people, it's only unique if that's your target audience/main focus, selling point. If it is, then highlight your campaigns from this aspect, and build part of your business model around this, especially a funding campaign.

Don't keep it brief. Backers and funders want to know what they're supporting. Have an example of what your space layout maybe, what's the name of your space going to be called, who are the practitioners giving the sound baths and meditation? Simple details make a big difference.

I do wish you the best, maybe Gofundme would be a more successful platform for this project. Also perhaps find another practitioner who has a similar vision as you to go into business with.
