Create and finish galleries

This is my site as it is: http://dev.hemera-collective.co.uk.gridhosted.co.uk/?p=927

Go to Exhibitions and you will see that 4 galleries are there. There are two more to add to this.

Two of the images are incorrect and need changing. The title of the exhibitions is wrong as needs changing. And the order of the images is wrong. The top two images are landscape but displaying as portrait, this size needs adjusting.

When you click on the image the first two lines of text are formatted wrong in each gallery, this needs adjusting.

The size of the main image in the slideshow is far too big and needs adjusting to 600 x 450 px.

The Portugal exhibition has a link to a random youtube video. This needs to link to a specific Vimeo video.

Two more galleries need to be added, one with less roughly 5 images and text, and another with about 15 images and text.

I will pay £20 to complete this work and no more. Please do not accept the job and then ask for more money, because this is the unfortunate experience I've jut had with a designer.
