35k isn't a lot of gold but there is just so much stuff in my chest that I can sell
you can make a lot of profit off selling things by enchanting and/or improving them beforehand
neither soul gems nor raw materials are worth a lot themselves, so you aren't really losing much by doing this
and if you have a bunch of raw materials, after improving stuff, then make armor or weapons out of that (then enchant/improve if desired)
I don't usually bother with it tho, I have enough money as it is
