I'll definitely be watching this topic because it interests me too.
Maybe you should have posted this in the mining section though.

Giving a block finder bonus that reduces other miners payouts may deter smaller hash rates from joining your pool.

If you just give the block finder a flat bonus, and everyone else gets paid normally, how will you make that up without going broke?  What kind of fee would you need to set to make your own ends meet and payout block finders?  Higher fees are going to push people away.  PXC Dev pools are 2% but a 1% fee pool rides at or above 50% the hashrate daily.  Two reasons for this, 1. lower fees, 2. higher pool hashrate reduces pplns variance.

Option A:  This is not a bonus, its a redistribution of how 100% gets paid out.  If anything, you would reward high hash rate while penalizing lower hash rate miners. 

Option B:  Most transaction fees I've gotten from PXC have either been 0 or .1 PXC.  Not really a bonus if the block doesn't have a transaction fee.  At .1 of 50 is only a .2% bonus for finding a block.

1% fee is good.  Promotions and giveaways are too, just make sure all funds spent are accounted.  Being honest about donation funds goes a long way in how people feel about donating coins.

update i have been looking at dedicated servers and domain names i am thinking of the pool being (cryptomining.co.uk/pxc)that way if i want to set up more pools i can any ides ?

have been looking at dedicated severs and a good 4 core sever is around 100  gbp a month and should handle 100,000kh/s acording to what i was told so a 1% fee should cover all costs mabe able to lower it after a month or 2 just concidering the offer to set me up a pool for 50 ltc seams like alot of ltc curent price of 50 ltc 160 usd  for what im told is a few h of work
if there anything anyone would like a poo to do that a pool is not doing now ?

Don't think anybody is going to want to use a pool run by somebody with zero clue about how it works.

to cover your server costs, you'll need 100 gbp a month....so 150 bucks...or 50 ltc.  That means your pool needs to collect, monthly, 5000 LTC's in order to maintain costs at 1%.  5000 LTC is 100 blocks.  That is at least 3 blocks a day.  Your pool will need a hash rate of at least 50 MH (this is just for LTC) to meet that demand.

I know you're doing PXC, but the idea is still the same, just harder to accomplish because there are way less people mining PXC than there are LTC.  You're going to have to be pretty enticing of a server to pull people away from what already is working for them.  Located in EU may be to your advantage in this situation as the only other EU PXC server is the dev one.  However it usually has less than 50 MH.

In my opinion, your server costs are too high.  Start out with a much smaller package if you can, upgrade when you need to and can afford it.

just worked it out with 20,000kh on pxc that would get nearly 100 blocks aday  so i would get 50 pxc curent value 1ltc sever is good for 100,000kh+ so that is 5ltc a day that more than covers it

i would rather go for the biger server because i can always start a a difrent pool aswell on the same server and changing server meens downtime
having 1% fees and a good sever would meen i should get a good amount of hashrate on the pool

it is expencive because thay charge for the sever set up
