Hi Sir,
I have gone through your description and I am able to do your job in about no time according to the job description.
I have already done these types of job. I can assure you the score above 70. But attaining above 80 is difficult because it needs image optimization and all. It is generally done at the time of web development. If it goes above 80 it is fine but I can assure you above 70.
What you will get?
* You get standard quality work
* You will get technical support(After payment)
Waiting for a positive response!!!
Regards,
Jayant Kumar.
