Hello Christina
Welcome to Wab!!
What a fantastic opportunity you have there!
I wouldn't know where to begin but there are many knowledgeable people here who will be only too pleased to help!!
Don't forget to take photos at different stages so you can see how much hard work you've done as well and then maybe upload them here so we can see how you are getting on.
Look forward to seeing you around the forums and good luck with the garden it sounds like you are already having success with all the birds that visit now!!
