What i have learnt and conceived so far, u want a job and u want to carryon with your studies also.
in this case, i'd suggest you to apply for govt. job.
with your qualification u can get a job in grade 14-16 easily and in govt sector working hours are from 8 am to 3 p.m, so u'll have enough time to attend evening classes.
as far as what u should do is concerned, i think u should start with short period internationally recognized certifications, like MCSE, JAVA, Oracle Financials(it could be a bit expensive) etc.
these certficatins would allow you to get admission in any foreign university on full scholorship basis and u can have the life u,ve dreamed of.
a recent job advertisement that i,ve seen was from social welfare department govt of punjab. i am not sure whether they'd consider someone with sindh domicile but u can atleast call them up and get details about it.
u can call on this number 042-9204157-8(Mr. Nadeem(Assistant Director Accounts or Mr. Yameen will attend the call)) its the number of Punjab Bait-ul-Mal, this department is working from within the same building in which social welfare department works.
they can give you the telephone number of Miss Farah-Assistant Director Admin of social welfare and you can know whatever u want to about these jobs.
wish you the best of luck brother...
