I've designed a solenoid in FEMM software , but can't manufacture a single qty  .I've found lot of similar solenoid from ebay.com but i'm searching for local suppliers  .

Important : please don't suggest me solenoid locks - I need pull type solenoid only - I've designed the other lock mechanisms

The requirements are :
Pull force : 10 N @ 5mm
Stroke : 5mm with spring return
Voltage : 12V / 24V
Power : 10W < power < 30W

If anyone has spare solenoid with these specification or know any manufacturers who can sell at Single qty. please PM me.

will this be of help, i'm going there on friday, do you want me to find out the actual price.

@sahilkit thanks for your help. But the solenoid that you've specified has only 0.8N holding force. I need a solenoid with pull force of 10N @ 5mm and holding force of greater than 20N

i will find out if they have bigger models
