I would like to have my drupal commons website themed to look different from the default, need to change all usernames to real names. Loggintobogan and realname modules are already installed, however username option has to be removed from login and registration. All modifications should be done such that upgrades will not affect the alterations. At present there are no users, the site is now intended for my friends and colleagues. The domain name and site name will be changed after it is themed. So leave room for logo and a 12-14 letter site name. Most important component of the site is profile and should be default. Activity stream is not needed. Give me a reasonable quote. I cannot afford big payouts.
