I know you don't want to wait, but this spring I am replacing my 55 Gallon with a 20 G sump and most of the equipment. Once I make the switch to my new 150, I will be selling everything. However, it won't be a full setup. you will need to buy rock, lighting and a some flow gear. It will consist of the tank, sump, DIY stand, skimmer and the return pump. You would need to buy some type of power heads, Lighting, and rock. I am in Columbus Ohio, so it may be a bit of a drive to get it but I think you would have a better start and you could use the next several months to slowly start saving money and buying equipment.
