Hi memyselfandi,
Firstly welcome to vb.org!
We set the permissions like this because technically vb.org aims to help licensed vb owners hence the service requests forum is created for this purpose. Please note that your case is a very big exception and in most cases a service requester would be a licensed vbulletin owner.
But I understand that sometimes some people need such services (or at least to get a quote) BEFORE they purchase the vbulletin as their decision about the purchase might depend on the quote (or service) they'll get. In such cases, we make an exception for that poster and allow him to post his message there. If you like to get a quote for a vb hack or service, I think we can also make an exception for you too.
However please note that Jelsoft is already giving an vbulletin installation service so if you want to hire somebody just to install your vbulletin, you do not need anybody!

You can get this service while you are purchasing your vbulletin. But if you need more services of a coder and if your decision to buy the vbulletin depends on this, please let me know the details and I'll see what we can do to get your post moved there.
