k2 tag cloud add a show more button

Hello
i use creativity template, which is great, and k2 for showing articles. This is a magazine site which is manipulated like this:
i have a menu called issues. Then submenus called issue 1, issue 2 etc. The submenu issue 1 is a k2 user page (blog) type. I didn't created users (authors) because i often have articles that are written from 2 or more authors and k2 assigns only one author per item. So my submenu issue1 although is a user page blog item it doesn't show user's info, as i have chosen not to show.
Everything is just fine.
My problem is that i must somehow show all my writers, so the user can see who has written articles in my magazine, and by clicking on writers' name to see which articles this writer has written. I implemented that by using k2 tags. I created also a category called writers and assigned an item called writers name to this category. Then i published k2 tag cloud module to the sidebar position. I want to show all writers, so i went to k2 parameters and set a big number lets say 200 to tag limit and assigned tag cloud to take data from category writers. So far so good.
The problem is that now i have a big tag cloud which is not aesthetically good. I would like to minimize it somehow by adding a show more button, so when a user clicks on show more can see the whole tag cloud in sidebar position, without changing page. Is that possible? Could someone help me please?

I’m afraid that modifications such as this require extensive changes to the theme’s code; I do apologize but such large changes are custom work that are beyond the scope of our technical support.

ok i understand this. Do you offer custom work? If yes would you please send me a pm?
Thanks
