Without knowing all of the variables to your project, it's difficult to give a 100% accurate proposal, but here's my best approximation:
I've owned an SEO agency for the previous 13-years, and added omni-channel customer journeys, automating them once optimized. My knowledge, hardware, and software which will be utilized to complete this task are a perfect fit. Being able to send 20,000 text messages per hour to contacts will provide immediate results in gaining not only a large quantity of leads for you, but of high quality, too.
Per your question of the number of leads I can provide, I can't answer that unless I know how far along in the sales process you're looking for the leads to be. If leads to you mean ANY HOMEOWNER who responds to an initial text message, I can provide hundreds daily. If a lead to you means a contact engaging back and forth and meets several requirements, I'd need to know what those requirements are.
Additionally, by embarking upon an omni-channel approach and inserting the capability to send upwards of 1 million cold emails per month, large quotas can be hit very quickly. Depending on whether or not this will be a long term project, I also own roughly 100 websites, and can create scores additional in an effort to generate higher quality and an increased quantity of engaged leads to send your way.
Talk to you soon,
Josh
