Try native forums and services to hire BEFORE using anyone here. Look for real experts in the field.
I had 2 experiences right now. First item I posted here seems very easy. I got offer of $150 from here and more and days to complete. The item already had previous stuff done in form from other developers and I did all the server work myself. I got ahold of the original plugin developer off github. He stated it would take a couple hours and cost $30-35.
Second was a much harder project. I expected to pay $1k on average for what I needed. I got offers here of more then 1k. I decided to check another place and look for people that specialize in that work. That are tested and qualified for what needed to be done. After about 3 people I was talking with one and he understood exactly what I was looking for and needed. I was expecting a high price tag and all tho he said it is alot of work, price was $350 and another guy got back to me that was $375.
While it was something hard for those that dont understand it, its not hard for people that specialize in the field. Its just another day and something they are already used to doing and understand.
Looking for work on here just netted people with no experience in what needed to be achieved.
