I will come to your users group (PerlMongers, dynamic language meetup, or whatever) and talk about any of my modules, any topic, or give any talk I've given before.
Topics include but are not limited to:
B bytecode hackery in general;
Perl for the Las Vegas gaming market (my best received popular YAPC talk);
Tempe Bike Count planning and data analysis;
Scaling webapps on OpenSSI Linux clusters;
Automatic code generation with Markov
Chains chatter bots and a hacked Test harness that takes floating point test results;
"Perl Stole everything it has from SNOBOL" (comic/hyperbole but educational);
autobox::Bless (essentially an Acme module);
Math::SVD for building recommendation engines;
programming the Atari 2600 using Perl;
and of course, developing extensions for the WebGUI CMS
Banner on the community development portal in thanks for making the community release of wG8 possible. The banner will run for two years after the release. This option is for consulting firms providing WebGUI solutions, hosting companies supporting WebGUI, individual WebGUI consultants, and other providers.
Title sponsorship. I'll establish a site for the community development process and prominently display your logo there and give maximal credit on the github project, encouraging people interested in running this CMS for their own use to use your hosting platform.
