Grid dashboard EA

hello I need to create an EA with Dashboard 

i would like to find a developper

who has done at least 300 jobs and free for working quicly.

who asks all the necessary questions before the project.

who can carry out the work in stages and send me the prototype at each stage so that while he is working I can check...

and above all not to encounter a problem at the end...

the EA have to work with all pairs and cft cripto etc...

this EA have to do grid of BUY and SELL and manage all trade together. 

( from the dashboard => 1 I can put all the parameters - 2 I would also like to be able to modify them during the realization of the trades of the grid.)

and for all parameter insert 2 buttons that will allow 1-see on the graph and 2-executions )

1 The EA define the MID-P of the grid ( with 3 method)

2 The EA define the level 1 and the level 2 of the grid level1 define the price of BUY1and SELL1 

level 2 define all next BUY and SELL

3 The EA define risk of the first buy or sell according the rules. and for all entry.

4 the EA use hiden order or pending order according the spread.

5 for calculation of risk  the EA used also the fixed cost of each trade ( commission + spread)

6 the EA use Break even,  trailing stop and target for all the grid 

7- etc...
