Sounds good but there are some main questions you need to be able to answer.
Can you get a suitable website built to target this audience?
I believe you would need it be a very user-friendly website for the people you are marketing it to.
What competition have you got and how can you overcome them?
Yoiu really need to take a look at this. Ebay is obviously one of your main competitors. Why would the people of your area choose your website over Ebay?
You need to be able to have a few reasons it will be better for your taregt market.
Will you be able to advertise and be able to alert the local are of thtis?
As it is marketed in one area you will have to do everything possible to get them on-flyers etc.
