Greetings,
I'm a Wordpress Developer, with 4 years experience.
I'm not familiar with Classipress Theme, but every theme is the same, because it's working under WP.
So its very easy to make child-themes, and make the kind of changes that you want.
I will make a Child Theme to make all changes that you want.
And also functions with hooks to make some changes described on your project.
I've just left my previous company to start as a full-time freelancer.
So I can work on this full-time for 4-5 days, to finish everything really fast.
Some details about me:
Name: Diogo Gomes
Skype: diugogomes
Location: Portugal
Time Fuse: GMT+1.00
Cheers,
Diogo Gomes
