Joomla, Joombah and Jomsocial modifications and site testing

I require, my site to be tested for errors, a report to be compiled and these to be fixed. I am running Joomla 1.5 which has Joombah and Jomsocial installed on the same directory. I also require the site to be optimised, along with CSS optimisation if necessary and the sites to load and operate faster and more streamlined. I also require old modules or unecessary items to be removed. I require the jomsocialtoolbar to be updated so that it links to various actions in Joombah from Jomsocial and visa versa. If this work goes well, I may well ask for further work to be done.
