Hi, I read your job description. Now I will give you some tricks so that you can fix it your self.. This is very easy work.
First you go to the revolution slider which situated on the left of the admin bar.. You select the slider which displayed on your home page then you click it . Now you can see four picture, desktop, notebook, pad and mobile icon. Select the mobile icon and which box delay fix the time on below of the slider and also fix time of thumbnail or swiped...
Please I requested to you try it, if not learn something new..No problem if you give the work I can do it within 1-2 hours for 20 $.
Have a good day..
Thanks
