You're going to have to put forth a little effort here.
You can easily use Google to find out a good starting price for your laptop. I found a link first try. $1500 USED is a good start w/o the software. What did you pay for the software? Just sell it as that since you've not used it that long. Be sure you're selling the software in accordance with the EULA's as well. If it's academic software, you'll have to sell to a student who can prove their status.
Also, do not solicit for people to buy it when you don't even have a price.
Familiarize yourself with the
Traders Rules as well.
