Hello,
The conflict you're talking about is quite common when using John Godley's plugins (i.e. HeadSpace and Redirection), as well as a couple of others, so I am afraid that, once the problematic plugin has been identified, you will need to seek an alternative. As for the buttons, I would probably go for a quick fix, given your budget. Please, contact me with more information on both issues.
As for my references:
I have thirteen years of experience with WordPress and seventeen years of experience in web design.
I worked as a web designer for a local branch of Lush Limited from 2006 to 2010, and further on I've been mostly freelancing. I had clients among some big names in the independent music and film, as well as a local branch of Coca Cola, for one of their guerrilla marketing websites. I have worked with people all over the world from 2000 on.
As you can see, my English is almost flawless.
Looking forward to working with you,
I.T.
