SEO For U.S. Website

Looking for expert in SEO who speaks good English. We have website that markets tiny homes that we manufacture. We only want to rank for inside the U.S. - not worldwide. We are after solid leads looking to buy tiny homes. These would be people who are in buy mode or at this minute looking for a tiny home to buy. We are NOT looking to rank high for the sake of ranking high. The keywords for ranking must be geared toward buyers. I want at least 5 reputed company testimonials - ones I can talk to. If you can't give me 5 to talk with that meet the reputed company below, do NOT apply for this job. Also, those reputed company testimonials you give me MUST be in a similar situation as us, meaning, they are ranking for across the U.S., not just their reputed company and surrounding area like a dentist or a criminal attorney would want. Next, I want to know the approximate time it will take to rank for keywords that will generate leads. We can discuss what those keywords would be and you can give me an estimate. Next, my site is hosted on reputed company currently. Is there any reason that platform can't be used? (ie. change to reputed company) And if so, why? Next, what reputed company of guarantees can you offer? Meaning, for example, can you have us ranking reputed company-type keywords on page 1 in say, ....90 days? Note, this is just an example, but what can YOU guarantee? Next, assuming we start with you, reputed company would you start, what would you need? What can I expect from you? Etc. If you give me what I'm after at a fair price, I will continue to use you for your services. Lastly, do NOT ask me what my budget is. You tell me your estimate in costs. Apply tot his job
