Need Guidance... a lot of it too!

[GameLord]

I am an active member on several boards and have grown to love the vBulletin style.
Now I'm planning to set up my own forum (yeah, so what's new?).

I already have purchased the domain name and am now ready to buy VB.
The trouble is... I don't know what I must do next or where I go from here

I know I need a hosting service but I don't know which one I must sign up with.
A lot of people have offered a lot of advice and a lot of names - but I have no idea what I need to look for when deciding on a host.

Here's some info from my side:
I am in Singapore.
My forum will have around 3,000 users.
I won't host any video or audio.
I won't have avatars and signatures.
I don't want a dedicated server.
I don't expect any income from the forum.
I can spend US$10 a month on a host.

Would some kind soul tell me what to do next?
After I sign up with a host, how do I install VB on their server?
Should I get a host in Singapore or in the US?

My computer knowledge is very limited but I am not going to be discouraged!
