Know-How Exchange : Student Questions

hi all, I'm doing mba. I stuck in my topic. T_T
I want to change it. My adviser is hard to accessible.

What I'm doing are about "an analysis of the worldwide business and marketing strategies for ebay sellers".

My project are included: marketing plan for ebay *sellers* not the ebay site but ebay users. I chose the business then analysis of that business internal and external. Proposed with the marketing plan (not business plan). Finally I've feasibility study to compare with the normal e-business(my shop .com).

My adviser suggest me do to like I want to sell things online and ebay is suited for me then compare with the other e-Business tools(I selected oscommerce then buy domainname). My shop online is hard to sell when compare with my ebay store. I'm start just a month with no advertising, my adviser said it is great to compare when ebay has them all. I think it has no meaning, what should be the results, but my adviser need for something that can "measure", "evaluate". I wonder what time should I spend. All of my friends graduated except me cuz I don't have a good results to compare. Should anyone please suggest me what I should to do with this.

I'm confuse with the research methodology too, should I follow marketing research model: purpose,plan,performance,process,and prepare to do the research. I did not do the research for eBay. I'm seller and want to find the marketing strategy for someone who sell things on ebay. What model should I follow SDLC? I'm really lost. T_T

The purpose that I want to do is that ebay has good marketing tools which I want to include and I think this's useful for other ebay sellers.
