I will do this job as you want that you may pay me the security deposit 75$ that when you pay me, at the time when I finish your job as you want, it would be counted as paid from the payment you promise me to pay.
and the payment may be done half when the job will be done half, the next will be done when the next job is done.
and send me the job so that I will plan the job.
bye good luck.
