1. Not all Israel people are bad. Some pay whatever you ask them if you are talented enough.
2. Be honest to the client.
3. For web developers (not designers): Host the site in your own server and give them admin access but no file or direct DB access. When they are happy, transfer the site for them.
4. Use GIT or whatever version controlling system you find easy. Most clients do not know how to use one but they understand it's useful to have one, and usually pay you to set them up for them (now don't charge them a hell lot of money - they have already paid you probably even with grands).
5. If the task is pretty small and straight forward, just explain them how to do it yourself. They will probably not pay you for this one (nonetheless, it's a small project). But you have a higher probability of getting selected for their second job.
6. Include licenses and credit to others' work you use. They will not find it useful but will impress them that you are honest.
