Price this system plz

I think he's talking about a mysql admin panel. Useful for backups and stuff like that. I'd clarify the concept of being able to change the amount charged per subscription. Is it a universal change, or is he looking for categories of users?

I line in an area of the US where the cost of living is slightly higher than average. Typically charge $50-$100 US per hour. Subcontract all my graphics work to a very talented group who get $70/hour. I get $5 of that fee. they also charge for initial discussion. I give the first hour free.

I don't charge for learning time, but I've got some sophisticated stuff "in the can" that I can reuse rather rapidly. I charge more for that type of material although it can take much less time to implement than more trivial custom work.

Some clients have me on retainer to do a certain number of hours of updates per month/quarter. Charge a lower hourly rate to them as it's a steadier income.

For the site you spec'd out, I'd start at $1000 as an estimate. Number of pages, quality/complexity of graphics, and logic to handle multiple categories of users, and excessive user administration capabilities would increase the cost. The client needs to be aware of that up front. He also needs to know that changing his mind after work begins costs money, but I'm sure that holds true in Egypt as well.
