I'll create a customized form (page or post and/or widget) on your site, with whatever design option you like using the CF7 (contact form 7) plugin, the most popular WP form plugin on the web. If you don't have the plugin installed, I'll install it for you. Using this plugin, I can also create an opt-in form, where potential visitors can subscribe, and you can keep track of them via email or through an online email subscription list, like MailChimp. I can also add an easily accessible DB on the WP dashboard where you can also keep track of them.
If your form is more than 15 fields, then please send me a PM before purchasing since this may require more than one gig order.
If you require a multi-page form (not a multi-tab), then also send me a PM before purchasing so I know exactly what type of linkage will be required, etc. It may also require more than one gig purchase, so please be advised.
*IPORTANT* I get some people asking me for high form functionality, i.e. calculation and summation between fields; or, when a person enter a city or zip, the country or state shows up on another field. Currently I do not offer such functionality.
