Website Widget Integration

I have a wordpress website, and would like to update a part of the site with a widget I have received from another website. I am yet to receive the widget, but when I receive it, for legal reasons, it must be online within 24 hours. So I am looking for someone who is able to be responsive when I am able to get the green light. It should not be a complex bit of work and should take someone less than an hour. However, if it all goes well, I will do a lot more tinkering with the site.

Many thanks,

Tom
