Hi, I am sure that I can get this HTML5 app up and running for you as you require.
I used to keep wicket for my village and had great fun, I'm from Wiltshire and as last man I fully understand that when I go out to go in I may be out and come in :)
I am currently working on a tour guide app for the island of Cyprus on a part time consultancy basis, and can provide you with the URL, as and when necessary.
Although I am based in Cyprus we are only 2 hours adrift and my working hours are very flexible.
We can keep in constant touch via Skype or similar if you would like in order to ensure continuity and a good audit trail.
I look forward to hearing from you if you feel that I can assist you with this.
