Workshop is a D.I.Y. community for discussion about projects around the house and garden. Our talented members are contributing their own projects here all the time and I trust they would be more than happy to assist you with tackling this project yourself. Perhaps you might like to start by showing us some sketches of what you were after. Our members can then advise the best way to go about the construction.
For finding someone in your area that could build it for you, it would be better to try a site like hipages or Airtasker.
Please let us know if you have any questions about the project or need assistance in getting started.
So you are aware, I've removed your personal details for privacy reasons as this is a public forum.
