Converting Honda GX160 Engine into Generator

I am thinking of buying car pressure washer and dual action polisher but the place where my car is parked does not have any power outlets whatsoever and I'm wondering how can I power, car pressure washer and Dual action polisher.

I can't tap into any existing lights or electrical devices. Everything is bolted down and it is not permitted. I don't want to run anything off my car's battery.

Only possible solution is generator.

I have enquired some of the local Honda dealer here in India and cost of the 3kv Honda Generator is more than $1500 and I not willing to spend so such money just for washing my car. Here is the link http://www.industrybuying.com/inverter-generators-honda-siel-EL.PO.IN.170498/

After doing lot of googling I have stumbled upon a site where they are selling generator built on Honda GX160 engine. Here is the link

But I am not able to find generator based on this engine. So I am planning to buy this engine and convert this into generator. Problem is I don't have any knowledge about all this stuff. So I need forum help. My questions are

1. What are all the things required to convert this engine into generator.

2. Wherther power generated by this engine will be sufficient to power 1800 watt/220 volt pressure washer. I will not be running both the machine together.

3. is their anything I need to take care off.

Thanks in advance
