It's far too hard to quote a price for the job without understanding the scale of it. I would just calculate it on an hourly wage. Logos, icons etc take time, I would work for $25/hour....so based on the size of the project you can work from that.
Lets say it takes you a week, working 5 hours per day. That would be $25 x 5 = $125 and then $125 x 7 = $875.
