I have not coded a complete vbulletin template yet however I would like to learn the in's and out's of the template system they use. I coded my first HiveMail skin this for a client that was delighted with the work I produced, hence I believe I won't have alot of trouble with the vbulletin template.
Please look at the following thread I recently created to show I am available for work and the services I provide. It has my contact details if you are interested in choosing me to code your vbulletin skin:
