Sorry to hear about your dad mate
Well done with your post in this forum, you will be just fine, i've been doing marketing for about 25 years now and there are some great replies above.
Price and quality match everything, get a good website up ASAP and start marketing online, if you are looking for a SEO
http://www.honestseo.com will give you some guide lines for picking a solid one.
I my personal experience, the fastest and cheapest way to boost business development is website + pay per click advertising
You could use Google and overture, but dont pay more than $0.30 per visitor. Rather then use services that I advertise on my website.
My company (based in the UK)
http://directtraffic.org does pay per click advertising with results that do not appear in the sponsored links of google or overture, but in the web results. this sort of service will help you save per visitor and direct loads more traffic to your website.
Since we are based in the uk, it might be best to use someone from the USA, since they will be able to understand your target market better.
If yould like, I could look for some one that does the same thing over there.
All the best mate, keep all your costs down and only use targeted marketing until you have money to waste.
