I am in the process of gearing up to start doing bespoke work again - if you'd like me to make something for you, let me know in the first instance. For the immediate future, whether or not I take on a project will depend on a) whether it interests me and b) how much actual work is involved.
IF YOU HAVE A QUESTION ABOUT HOW A MODULE WORKS then I shall endeavour to help you if I can, but bear in mind that if you've got something really old then I may not be able to provide you with much (or any) information. Generally, if a module is 'supported' then there'll be information on my Github page
I endeavour to answer all queries as soon as possible; you're most likely to get a quick response during UK (GMT) business hours.
