I'm in need of help

Hello everyone I recently bought the budget smartphone wich is not actually that bad :D I also rooted it with a pre-rooted stock rom but it actually is the original touchwiz wich is ........ well touchwiz it gets slow after a week of using the phone I also installed TWRP on it wich works perfect. I also found alot of links on google claiming that they got a custom rom for the j100h (btw yeah this is the model i own) especially lollipop but all the links i found use surveys and they say that there is no survey available for your country (I live in Europe Kosova to be exact) if they are real could somebody please make a mirror or send me it (somehow), but I got the GenNxt pre-rooted stock if it helps I do not think that there are any custom roms for this device (not yet) I saw that the creator of the TWRP for the j1 said that he is building one (cm12 to be exact) but I do not think that he would be able to create it ( maybe he can I hope he can) if anyone could create a custom rom for this device I would be happy if it would be cm12 (lollipop) I just need to get rid of touchwiz it's way to laggy (I do not have any experience building roms (if it helps to know).

Please reply ASAP. Timidms
