Tips for advertising my new online business?

[Chris]

Hi in about a week a will be starting my own online business. I will be selling hockey tshirts and hats. I'm looking for advice as to how to get my website out there and for people to buy my stuff. I already have a twitter account with 1500 followers and a bunch of people that are looking forward to buying stuff based on the pictures ive uploaded but I know I can't count on twitter and facebook to get me the amount of sales I would like. I know that forums might work but I don't know which ones and other than that I just have know idea how or where to advertise for cheap/free. Any advice given is appreciated! I will give the best answer out tomorrow!
