Hi Mike, Welcome.
I too am planning to start up shortly and also on a tight budget. My advice to you is don't commit to any machine/brand till you have hung around a while, looked at the many companys about or spoken to local cleaners. When I first started looking into a machine everytime I got info sent through from another company I was sold on that one

Now I've narrowed it down to a couple, If you want I'll email you all the company websites that I've looked into regarding machines, also consider factors such as location of supplier. Through this board I get great advice both on the forum and email and one company in particular gives plenty of excellent advice and has offered a machine demo
My main concentration at the moment is marketing, A very important factor, just search the boards for great advice and don't be afraid to ask, everyone is helpfull and it's a laugh when they start arguing between themselves, It's usually the case that these guys are agreeing about something totally different on another thread

Again through this board I've been sent some brilliant samples of flyers and made some great contacts/mentors who seem to always have time for my queries
Personally as far as training goes for me I plan to do a hands on course as soon as I can afford it, Then I'd like to get either NCCA or IICRC not only because I believe you need to know the theory behind c/c but I believe it looks good to firms when marketing especially commercial. Also when I first joined this board a very nice guy offered to take me out with his organisation and show me the ropes so hopefully I'll be able to take him up on this offer soon.
As I have no cash yet and my full business depends on selling my vw campervan I just read read read old posts on here,print them out and ask if I'm unsure about out. I got myself a craftex manual from
www.restormate.co.uk and registered with shell live wire a business starting company, free advice and tools, This way I'm always working on my planned business and hopefully will get it right
I'm hoping to be able to afford a second hand van out of my vw sale and an old mate of mine (soon to be rekindled

) Sprays vehicles and is a dab hand at graphics so I'll have him tidy it up and personalise it, I've seen a few on autotrader.co.uk around my price.
I wish you all the luck mate and I can't offer much help but what I can is yours
Andy
p.s. Make sure to check out the shell live wire, on a c.d. they send out to you there is a comprehensive list of many organisations that will help you start up, Many offer grants for starting up a business after redundancy. I can also email you this list if you want.
