Are you sure all the site on your portfolio you actually made as i think the seek4singles is not one of yours.
Your site compared to some of the portfolio ones is a bit of a downgrade. If you are saying you made certain sites and you have not made them be careful, if they find out you are in trouble.
People will think you made the site if you have that in your portfolio. Just mention that you did the ecards for them and all will be good. Also make sure the company ok it.
