That’s pretty involved; there’s not going to be a plugin or a quick set of instructions to do all of that. I’d recommend hiring a WordPress developer.
thanks for the reply, it sad. I would like to do it by my own
Well, maybe you can, if you get some really good help and take it step by step.
You might try posting on one of these WordPress discussion sites:
WordPress Sub-Reddit: http://www.reddit.com/r/Wordpress/
WordPress Stack Exchange: http://wordpress.stackexchange.com/
Also, there’s a plugin called Gravity Forms which allows you to do a lot of advanced stuff with forms – might be worth looking into for your project.
Someone else may jump in on this thread too.
I know this thread is old but have you ever thought about the plugin WP Online Contracts? http://codecanyon.net/item/wp-online-contract/7698011
Gravity Forms is definitely my first choice but this is a simple to install and get going alternative.
ApproveMe is a premium WordPress E-Signature plugin that is little more expensive than your average WordPress plugin but it’s well worth it. It’s priced similar to Gravity Forms however it’s main focus is on generating court recognized UETA/ESIGN compliant release forms, contracts and agreements.
When it comes to signing legally binding documents that could end up in court the last thing you want (for you or your client) is a document that’s not court recognized. Especially if it ends up in the hands of a Judge. If I were in your shoes I would ask the client for the extra money and have them go with one of the UETA/ESIGN compliant options. Especially since it’s their business that could be compromised.
