G'day mate, I realise this bid might be a little higher and a little larger time frame than a lot of the others but I hope that doesn't scare you off!
Looks like a fairly simple brief so it shouldn't be a problem to get done for you! A little bit of complex coding is required so that you can adjust it using HTML (instead of having to edit the PHP script) but I don't think we should run into any major problems.
All my work is custom and I only take on a couple of projects at a time, so I'm pretty focused on creating something which really suits your requirements. I can start immediately and have the project completed in four weeks, plus I will stick around afterwards just to make sure everything goes smoothly.
Look forward to hopefully hearing back, and good luck with finding someone!
Cheers, Scott
