Since this website you are posting on is specifically for adopting out pigs, I would think you would check the classifieds here for an adoptable animal, then try petfinders.org as well. Finally craigslist.org sometimes has people dumping their pigs when they get bored with them too.
I also recommend making a visit to
Guinea Lynx :: A Medical and Care Guide for Your Guinea Pig and read their "Care Guide" it's got priceless information that is up-to-date and valuable for all new and old pet owners. The site is managed by cavy rescuers and veterinary professionals who work with cavies, so it's as good as it gets for cavy information.
When I got my pig a year ago I spent weeks googling for information before I located their site and now I shout it from the rooftops!
By the way, I have a Cube and Coroplast cage I built for my pigs using grids from Target and the information provided at the
Guinea Pig Cages, Your Cavy At Home website.
What do you think?
I built it slowly starting with the upper level, then later on I bought more grids and built the lower level.
The upper level cost me $15 for the grids, and $10 for the coroplast base.
My pet store cage was half it's size, and cost me 3 times as much money!!!
Also helps to read up on cavy behavior here:

It sounds she is getting used to you! It will take time and some pigs never fully turn into lap pigs, others come to love their human time more than anything. The most important thing is to spend lots of short visits rather than one long one. They seem to have short memories and for some reason picking them up and holding them for a minute several times a day seems to have more of an effect on their tameness.
Also I always recommend this site as well:
Taming your Guinea Pig.
This lady has lots of good stuff on her page on taming.
