Joomla specialist needed

Hi, we operate a successful and global natural health website and require some assistance from a php/Joomla expert to get a few "niggly" projects out of the way

We have the following tasks that need completing in the coming week.

1) New database capture form that needs to be programmed to send an email with that data to a pre-determined email address(es)

2) A Character length limit being programmed for existing status update section in forum

3) Activation/Integration of a twitter feed to be incorporated in to the existing site

4) Create a backend upload system for a database of suppliers that will then appear as a live data within a page on the site

If you need any clarity, please feel free to ask

best regards

Lee
