Sort Functionality Issues on a WordPress Website Booking Interface

Looking for a top class IT programmer to resolve functionality issues on a UK holiday establishment's website that was recently created in WordPress. This applies above all to fine-tuning of an already created automatic booking interface so it preforms as it should, (flawlessly), and allows our guests to book online via this interface. Whilst we are not necessarily looking for a web designer someone with design talent would certainly not go amiss. We are certainly not after any person who would wish to re-design what has already been created by the person we previously chose to update our old website. Sadly, due to unforeseen circumstances this person couldn't complete the task to full functionality in some important sections. Please provide three website examples you created and that you consider to be your best. We are not interested in any examples based on templates made by someone else, or work that you cannot prove you actually created.
