Advisor Registering IP range + ASN

I plan on starting hosting and I am wanting to register my own PI of a /24 IPv4 range and an ASN I am after someone who is able to help me register a /24 and knows how to guaranty it (I am looking for an advisor) In other words I am looking for someone who has the experience and knowledge in PI registration and set up, to be able to "hold my hand" and tell me who to talk to and what to say in order for me to have my own IP space.
