Cross Browser Experts only need to apply

We need someone to fix our cross browser issues specially for Internet Explorer. Ensure that all links work and the format of the website is same in all the browsers. We also have a progress bar on our website which is already coded but is somehow not working properly. We have a Ajax functionality which automatically brings up region and districts moment someone enters a suburb - but it is slow we want it to be instant just like Google. We need to add some text below a field. We need to delete a line on Join Up Page and deactivate the tick box or automatically activate tick box so people do not have to click on it. Send us a PM to get the URL but we will decide who to provide this information to.
