Price Check Help

Hi I've recently gotten a new account from a friend and the past week I've been messing around on it and have gotten 2 50s, campain on legendary complete, and almost all armorer but recon (which I can get quick). But I plan on getting three to four more 50s on it the next 2 weeks and am curious how much 5-6 50s (swat, mlg, snipers, dubz, slayer, lw) would sell for with about 300-400 exp with less than 70 loses
plz help and let me know if interested

 

I would say at least $40 with all the 50's and low losses.
