chances of securing an ITA ? need expert opinion

[Feejay]

My point score in submitted EOI amounts to 60 (including 5 points for 190 state sponsorship) and 65 (including 10 points for 489 provisional regional sponsorship), however this point score doesn't include any points for work experience (even after having almost 6 years of work experience, my employer not willing to issue an experience letter) ;

 

In fact, I initially applied through mentioning experience and got 189 ITA, went through the whole procedure but HR refused to the DIBP calls due to which my 189 application got rejected and loads of money went down the drain, therefore this time I am willing to play clean by securing those 5 points by state sponsorship; I know 190 is a permanent visa and without experience it is not possible to 190 get invitation that's why my primary aim is to secure 489 ITA and move, then fetch a job and after an year or more file for permanent visa (887)

 

could any one tell me that what are my chances for securing an ITA for 190/489 category, I don't have any preference and willing to relocate anywhere (even at the low population suburban areas);

 

Thanks!
