Hi,
Read your entire job description along with the mentioned points, which need to be completed by 31st May - to be honest with you, being as an Expert and Experience Developer - I would definitely like to grab this opportunity, but without looking into the sites and detailed requirements, I can not commit you for accomplishment of the task with a given deadline, I am hoping you can understand this situation too.
Additionally, if you have not finalized anyone yet - then please share your suitable time and we can have a quick discussion to proceed straight to the task as you can see the urgency of the task. If everything is feasible then I will definitely try to finish them before the time-line and be transparent with you.
Carrying 10+ years' experience with JOOMLA + PHP Development, I have delivered numerous list of small tasks with a complete Bug-Free solution, so please allow me to assist you.
Looking forward to hearing from you soon.
