Bespoke programming to Wordpress website and backend. -- 2

We need a expert PHP coder to work on our clients complex Wordpress website. Please read our requirements carefully. Please do not send us spam / blanket marketing messages with generic portfolio links. 1) We have created a simple Newsletter signup form (in a lightbox) but we need you to hook it up to MailChimp API. (Another function on the website already exists for this, which you could use) 2) Make the list of pledges automatically order alphabetically. 3) Add an option to feature some pledges at the top of the list. 4) Create a new user on the wordpress CMS to add new Pledges & Opportunities to the database. (All other areas should be locked out for them) I have attached screenshots of the 4 jobs to give you a visual idea of what we need. Please provide me with ONLY 2 examples of customisations to a wordpress website you have done before. For example a customisation you've made to a plugin, or a simple database you have built. Any standard marketing messages will be ignored. Thanks in advance.
