online store selling imported textiles?

Greetings. I am taking a hard look at what it would take to import some very specific textiles and resell them on an online store. I believe there is a niche that needs filling but it will come down to whole sale cost. I have found some possible sources from internet searches but am new to this idea. Currently I have snagged an appropriate domain name and am working on a written business plan. I also have a call in to a local SBA office to also get some help. Any advice or suggestions would be appreciated.

Thanks,

Josh
