Looking to hire someone to simply update the graphics on my site..

I have 2 websites and I am looking for some help to update the boxes on my sites... I have a friend who has been doing this for me but it is becoming unreliable working with her..

My websites are www.kidschairworld.com and www.briannasbeddingandbeyond.com. The boxes I am referring to are the featured area boxes where I have my specials....

I would just need some pictures swapped out and to change what it says..If anyone here has experience with this or knows who I can hire that is reasonable please let me know.. thanks so much :)
