[LRUG] Chat Digest, Vol 55, Issue 12

Tue Aug 10 06:01:54 PDT 2010

Hi all

Just following on from my request at the meeting yesterday; I've built
rocketsports.co.uk on ruby (or rather my developer has!; and a great job
he's done I have to say) however he's unfortunately not able to commit much
time moving forward due his wife having just had a baby (great news!);
however I have a white label solution to build and launch, ideally before
October as I'm working with HSBC on a large event, that they're sponsoring -
that the white label solution will need to be ready for to organise!

So if there's anyone around for aprox 5/6 weeks solid (or if you have other
projects on perhaps 3-4 days per week - I'm quite flexible) to build the
white label solution on a fixed amount of cash and get this out to market;
and then if possible potentially ongoing on an hourly rate to help with
adding features and tweaking things, let me know.

I'm speaking with some good folks overseas but it would be great to have
someone more locally.

Let me know if you or if you know of anyone else who maybe interested.

Kind regards

Jonathan
