I would like to know what it would cost to develop a very basic plugin for my Socialengine websites.
The idea is to promote more members to sign up. I was thinking of a small floating screen that says "Sign up now!" , or something similar to that. The screen would be shown to all members who have are not logged in to the websites. Must be very light, load quick and also close fast if user was to close it.
What I need is something very basic.. please let me know how much it would cost.
